1. Financial Accounting & Controlling Errors (FI / CO)

FI/CO

Posting Period Closed (Message F5 201)

The financial transaction posting date falls into a fiscal period that is locked or not yet open for the specified Company Code.

Resolution

Open the open posting period variant in Transaction OB52 (Finance) or MMPV (Material Management period shift).

FI/CO

Balance in Transaction Currency is Not Zero (F5 702)

Debit and credit amounts do not balance out to zero in the transaction currency during document posting.

Resolution

Check tax calculation settings, line item line amounts, or rounding differences in the posting payload.

FI/CO

Cost Center / Controlling Object Requires Account Assignment (KI 235)

A primary cost element G/L account requires a CO assignment object (e.g., Cost Center, Internal Order, or WBS Element) which was omitted in the posting line.

Resolution

Provide a valid Cost Center or maintain automatic cost assignment default rules in Transaction OKB9.

FI/CO

Tax Code Does Not Exist in Procedure (FF 704)

The specified tax code or condition type is missing or not configured for the target country calculation procedure in FTXP.

2. Materials Management & Goods Movement Errors (MM)

Resolution

Configure missing revenue G/L account mappings in Transaction VKOA.

SD

Credit Limit Exceeded / Order Blocked (V1 150)

Sales order processing blocked because the customer's total credit exposure exceeds their defined credit limit.

Resolution

Review and release sales order credit blocks using Credit Management Transaction VKM1 / VKM3 (or UKM_BP in S/4HANA).

PP

BOM / Routing Not Found for Material (CO 634)

Production Order creation (`CO01`) failed because no active Bill of Materials (BOM) or Routing exists for the material plant combination.

4. Security & User Authorization Errors (SU53 / PFCG)

SECURITY

Missing Authorization / NOT_AUTHORIZED (SU53 Check)

User execution failed because the target authorization object, field value, or activity code (`ACTVT`) is missing from the assigned PFCG user roles.

Resolution

Execute Transaction /nSU53 immediately after the failure to capture missing authorization objects. Update user roles using PFCG or issue temporary access via SU10.

SECURITY

User Account Locked / Password Incorrect (SU01)

User account locked due to repeated invalid password attempts or explicit administrative locking.

Resolution

Unlock user ID and reset password in Transaction SU01.

SAP Errors Catalog Part 4: Complete Guide to IDoc, ALE & RFC Communication Errors

SAP Errors Catalog - Part 4: Integration, IDoc & RFC

Comprehensive guide to IDoc processing status errors (WE02/BD87), RFC connection failures (SM59), transactional RFC queue issues (SM58), and Partner Profile misconfigurations (WE20).

1. IDoc Inbound & Outbound Processing Statuses (WE02 / BD87)

STATUS 51

IDoc Status 51 - Application Document Not Posted

The IDoc was successfully received by the target SAP system, but the application posting function module failed due to missing functional configuration, locked objects, or invalid data values.

Resolution

Inspect error message details in WE02 / BD87. Correct the underlying data or configuration (e.g., missing GL accounts, locked materials) and reprocess via BD87.

STATUS 29

IDoc Status 29 - Error in EDI Syntax / Partner Profile Not Found

Outbound IDoc processing failed because no matching outbound partner profile, port, or message type configuration exists for the receiver partner.

Resolution

Maintain outbound partner parameters, port assignment, and message type in Transaction WE20.

STATUS 56

IDoc Status 56 - IDoc Number Assignment Error / Control Record Error

Inbound IDoc contains corrupt control record details (e.g., invalid message type, missing SAP IDoc type definition, or bad partner number).

Resolution

Check IDoc basic type definitions in WE30 and inbound partner profile setup in WE20.

STATUS 60

IDoc Status 60 - Error During Syntax Check

The IDoc segment structure violates segment hierarchy definitions, mandatory field checks, or data length specifications.

STATUS 64

IDoc Status 64 - IDoc Ready to be Transferred to Application

IDoc is waiting in queue to be processed (occurs when partner profile is set to "Trigger by background program"). Process manually or schedule report RBDAPP01.

2. RFC Destination & Communication Errors (SM59)

RFC ERROR

RFC Communication Failure / CPIC Error (LOCATION CPIC-Call)

The SAP system failed to establish a network socket connection with the remote RFC server host (host unreachable, wrong IP/hostname, or port blocked).

Resolution

Execute **Connection Test** in SM59. Verify gateway host settings, subnet routing, and TCP port openness (port `33xx` / `48xx`).

RFC ERROR

RFC Logon Failure / USER_LOCKED or Client Mismatch

RFC connection failed during the authentication phase because the service user account is locked, password expired, or client number is incorrect.

Resolution

Execute **Authorization Test** in SM59. Unlock the RFC background user in SU01 and update stored logon credentials in SM59.

RFC ERROR

SYSTEM_FAILURE during RFC Execution

An uncaught exception or ABAP short dump occurred on the target remote system during function execution.

3. Transactional & Queued RFC Execution (SM58 / SMQ1 / SMQ2)

tRFC / qRFC

Transaction Executed with Error in Target System (SM58)

A transactional RFC call failed to commit on the target system due to application errors, system shutdown, or database rollback.

Resolution

Review tRFC status in Transaction SM58. Select the failed LUW (Logical Unit of Work) and choose **Execute LUW** to re-trigger execution.

qRFC

qRFC Queue Blocked (SYSFAIL Status in SMQ1 / SMQ2)

An outbound (`SMQ1`) or inbound (`SMQ2`) queued RFC queue entered a `SYSFAIL` state due to a stuck entry, preventing subsequent entries in the queue from executing.

Resolution

Identify the root cause of the top entry in SMQ1 / SMQ2, resolve the error, and choose **Activate Queue**.

4. ALE Distribution Model & Port Mappings (BD64 / WE21)

ALE

Model View Does Not Exist / Filtered IDoc

An outbound IDoc was not created because no active ALE Distribution Model filter matches the source message type or data criteria.

Resolution

Maintain and distribute the ALE distribution model in Transaction BD64.

PORT

Port Cannot Be Opened (WE21 TRFC / tRFC Port Error)

The IDoc port assigned to the partner profile refers to an invalid or missing RFC destination in SM59.

SAP Errors Catalog Part 3: Transport Management System (STMS), tp Tools & SPAM/SAINT Patch Errors

SAP Errors Catalog - Part 3: Transport Management & Patches

Comprehensive guide to Transport Management System errors (STMS), transport tool failures (tp / R3trans), patch update locks (SPAM/SAINT), and transport import return codes.

1. Transport Management System Return Codes (STMS)

STMS

Return Code 4 (RC=4) - Warning

The transport imported successfully, but warnings were issued (e.g., generation warnings, non-critical table key mismatches, or missing non-vital dependencies).

Resolution

Review transport logs in STMS. Standard warnings can typically be accepted, but verify that target objects compile without error.

STMS

Return Code 8 (RC=8) - Syntax Error / Missing Dependent Objects

The transport import failed. Common causes include ABAP syntax errors, inactive target objects, or missing prerequisite objects (e.g., table domains, data elements).

Resolution

Inspect import logs in STMS. Transport the missing dependent objects first, re-activate required objects, and re-import the transport request.

STMS

Return Code 12 (RC=12) - Fatal Import / Database Error

The transport import process was aborted entirely due to severe system issues, database corruption, missing table spaces, or system shutdown during import.

Resolution

Check OS-level transport logs in /usr/sap/trans/log. Ensure the database is running and has free tablespace, then restart the import via STMS.

STMS

Return Code 16 (RC=16) - System Error / Transport Tool Crash

Transport tool (tp or R3trans) crashed during execution due to OS permission issues or system resource limits.

2. Transport Tool & Buffer Errors (tp / R3trans)

TP ERROR

TP_CANNOT_CONNECT_SYSTEM / TP_INTERFACE_FAILURE

The transport program tp cannot establish a database connection or communicate with the target SAP system instance.

Resolution

Verify database availability, test transport host connectivity in STMS (System Overview -> Check -> Transport Tool), and check TPPARAM configuration.

TP ERROR

TP_FILE_OPEN_ERROR / Trans Directory Permission

Transport program cannot read or write transport files in /usr/sap/trans/data or /usr/sap/trans/cofiles.

Resolution

Check OS-level file permissions on /usr/sap/trans and ensure the sapadm / <sidadm> user has read/write privileges.

TP ERROR

R3trans Finished with Error (R3trans -1)

Native transport data loader utility failed due to corrupted datafile headers or missing database dictionary structures.

3. Patch Update & Add-On Installation Errors (SPAM / SAINT)

SPAM/SAINT

Phase IMPORT_PROPER / DDIC_ACTIVATION Failed

Support Package Manager failed during Dictionary activation or primary transport insertion due to object locks or active database mismatches.

Resolution

Inspect SPAM error logs, release blocking object locks via SM12 or SE03, and choose "Repeat" in SPAM.

SPAM/SAINT

Queue Inconsistent / Prerequisites Missing

Selected Support Package or Add-on queue cannot be calculated because required prerequisite patches or component levels are missing.

Resolution

Download missing prerequisite Support Packages from SAP Support Portal and include them in the target queue.

4. Transport Locks & Transport Route Configuration

LOCKS

Object Locked in Transport Request (TR)

An object cannot be edited or transported because it is locked in another unreleased transport request.

Resolution

Check object lock status in Transaction SE03 (Unlock Objects) or release/merge the active transport request in SE09 / SE10.

ROUTES

No Transport Route Defined for System

Target client or system lacks a valid transport route configuration in the TMS domain controller setup.

SAP Errors Catalog Part 2: BASIS Administration, System Logs & HANA DB Errors

SAP Errors Catalog - Part 2: BASIS Administration & HANA DB

Comprehensive guide to work process bottlenecks (SM50/SM66), memory heap limits, Enqueue lock table overflows (SM12), system log alerts (SM21), and SAP HANA database memory faults (ST04/DB02).

1. Work Process & Execution Timeout Errors

TIMEOUT

TIME_OUT (Maximum Run Time Exceeded)

A dialog work process exceeded the maximum allowed continuous execution time limit (defined by profile parameter rdisp/max_wprun_time).

Resolution

Schedule long-running reports as background jobs (Batch/Background Work Process), or temporarily adjust rdisp/max_wprun_time in RZ11.

WORK PROCESS

Work Process in PRIV Mode (PRIV State)

A work process has exhausted local user memory and switched to heap memory allocation, locking the work process specifically to a single user session.

Resolution

Monitor work processes in SM50 / SM66. Increase Extended Memory parameters (abap/heap_area_total) in RZ11 to prevent process lockups.

WORK PROCESS

CPIC-CALL_RECEIVE_ERROR

An active work process lost communication with an external system or gateway process during a CPIC/RFC transaction.

2. Enqueue Server & Lock Table Overflows

ENQUEUE

ENQUE_REQ_TOO_MANY_REQUESTS (Lock Table Full)

The Enqueue server lock table is completely filled up, preventing any new lock locks from being created by application processes.

Resolution

Inspect active lock entries in Transaction SM12. Increase profile parameter enque/table_size in RZ11 and restart the Enqueue Server.

ENQUEUE

SYSTEM_GNT_RELEASE_LOCK_FAILED

Occurs when a work process attempts to release a lock argument that was already deleted or not owned by the current transaction context.

3. SAP HANA Database & Memory Allocation Errors

HANA DB

HANA Out of Memory (OOM) / Allocation Failed

SAP HANA database engine ran out of physical or allocated memory (`global_allocation_limit`) while processing complex column-store queries or delta merges.

Resolution

Analyze memory allocation statements in HANA Studio / DBACockpit (ST04 / DB02). Cancel heavy unoptimized queries or increase global_allocation_limit in global.ini.

HANA DB

Column Store Delta Merge Failed

Automatic or forced Delta Merge operation failed due to insufficient memory space or concurrent database table locks.

Resolution

Check DB alerts in DBACockpit and manually trigger a forced delta merge via SQL: MERGE DELTA OF "TABLE_NAME".

HANA DB

SQL Error 129: Transaction Rollback (Deadlock Detected)

HANA Database engine automatically aborted a transaction because two or more threads were deadlocked waiting for database row locks.

4. System Log & Storage Space Faults

STORAGE

Tablespace Full (DB Error -1632 / ORA-01653)

Underlying relational database cannot allocate additional space for a table or index because the underlying tablespace volume is 100% full.

Resolution

Extend tablespace datafiles via DBACockpit / BRTOOLS or enable auto-extend mode on storage volumes.

BASIS

SAP Gateway Not Running (SAPGATEWAY_CANNOT_CONNECT)

Application server cannot establish communication with the SAP Gateway daemon process (`gwrd`).

Resolution

Verify gateway process status in SM51 / SMGW and verify TCP/IP port `33xx` connectivity.

BASIS

Update Task Stopped / Deactivated (SM13 Alerts)

SAP Update Service (UPD/UP2 work processes) has been automatically halted due to a database failure or critical error during asynchronous posting.

1. Memory & Resource Allocation Dumps

MEMORY

TSV_TNEW_PAGE_ALLOC_FAILED

The system ran out of extended memory space while attempting to allocate additional memory for an internal table.

Resolution

Use PACKAGE SIZE in SELECT statements, free unused internal tables (FREE <itab>), or increase ztta/roll_extension in RZ11.

MEMORY

TSV_TNEW_OCCURS_FAILED

Occurs when the memory manager fails to allocate initial memory declared by an older OCCURS clause in an internal table.

MEMORY

Resolution

Verify object instantiation before invocation: IF io_object IS BOUND. io_object->method( ). ENDIF.

REFERENCE

DYN_CALL_METH_NOT_FOUND

Dynamic method call (CALL METHOD (v_method)) failed because the method name does not exist on the target class instance.

3. Internal Table Operations

ITAB

ITAB_DUPLICATE_KEY

Attempted to insert or append a duplicate record into a SORTED or HASHED internal table defined with a UNIQUE KEY.

Resolution

Use READ TABLE or INSERT ... ASSIGNING checks before inserting, or change table key definition to NON-UNIQUE.

ITAB
