Error Type: SAP Time Out Error (e.g., TIME_OUT short dump)

Common Cause: Transaction or report exceeds allowed processing time

Immediate Fix:

1. Note the transaction or report that triggered the error.
2. Use transaction ST22 to view the short dump details.
3. Check if the operation can be optimized (e.g., limit data selection, apply filters).
4. If possible, split large tasks into smaller batches.
5. Consult your SAP technical team about increasing the system’s time-out parameter if needed.
6. Use the SAP Error Assistant for tailored troubleshooting steps.

Understanding SAP Time Out Errors

SAP time out errors happen when a process runs longer than the system’s permitted time limit. This is a safeguard to ensure system stability and prevent one user’s task from blocking others. The most common scenario is a report or transaction that tries to process too much data at once, or inefficient custom code that takes too long to execute.

Common Causes

• Running large reports or mass transactions without proper filters
• Inefficient custom ABAP code or poorly designed queries
• Database performance issues
• Network delays or system overloads
• Low system time-out parameter settings

Step-by-Step Solution

1. Review the Error: Open transaction ST22 to examine the short dump (usually labeled TIME_OUT). Note the program and operation involved.
2. Optimize the Task: Try running the transaction or report with more specific filters or smaller data ranges. Avoid selecting all records at once.
3. Check Custom Code: If a custom program is involved, ask your ABAP developer to review and optimize the code for performance.
4. System Settings: Consult your SAP Basis team about adjusting the time-out parameter (rdisp/max_wprun_time) if frequent legitimate time outs occur.
5. Database & Infrastructure: Ensure the database and SAP system are performing optimally. Address any network or hardware bottlenecks.
6. Use Support Tools: Get instant guidance with the SAP Error Assistant or escalate to your technical team if needed.

Prevention Methods

• Design reports and transactions to handle manageable data volumes
• Regularly review and optimize custom ABAP code
• Monitor system and database performance
• Educate users on best practices for running large operations
• Adjust time-out settings only after careful analysis

Frequently Asked Questions

Q1: What is a SAP time out error?

A SAP time out error occurs when a transaction or program runs longer than the system’s configured time limit, causing SAP to terminate the process to maintain system stability.

Q2: Can I increase the time-out limit in SAP?

Yes, but only your SAP Basis or technical team should adjust the rdisp/max_wprun_time parameter, and only after evaluating the root cause and performance impact.

Q3: How can I avoid SAP time out errors?

Optimize your reports and transactions to process smaller data sets, use filters, and ensure custom code is efficient. Regular system monitoring and user training also help reduce time out errors.
