How To Fix UCT9021 - Error in BAdI implementation: maximum of 9999 steps exceeded

SAP Error Message - Details

• Message type: E = Error

• Message class: UCT9 - Workflow Connection

• Message number: 021

• Message text: Error in BAdI implementation: maximum of 9999 steps exceeded

What causes this issue?

The implementation of BAdI method CHECK_IF_STEP_FINISHED is incorrect:
At the latest when step 9999 is encountered, this method must return a
notification that this is the last step. This implementation of the
method does not do this.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Check the implementation of BAdI method CHECK_IF_STEP_FINISHED. Make
sure it returns CF_LAST = 'X' when step 9999 is reached, or earlier.

• What is the cause and solution for SAP error message UCT9021 - Error in BAdI implementation: maximum of 9999 steps exceeded ?

  The SAP error message UCT9021, which states "Error in BAdI implementation: maximum of 9999 steps exceeded," typically occurs when a Business Add-In (BAdI) implementation exceeds the maximum allowed number of processing steps. This can happen in scenarios where there are recursive calls or excessive iterations within the BAdI implementation.
  Cause:
  
  Recursive Calls: If the BAdI implementation calls itself or another BAdI that eventually leads back to the original BAdI, it can create an infinite loop, leading to the error.
  Excessive Processing: The logic within the BAdI may be processing too many records or performing too many operations, exceeding the limit of 9999 steps.
  Inefficient Code: Poorly optimized code or logic that leads to unnecessary iterations can also contribute to this error.
  
  Solution:
  
  Review BAdI Implementation: Check the code in the BAdI implementation for any recursive calls or loops that could lead to excessive processing. Ensure that there are proper exit conditions to prevent infinite loops.
  Optimize Logic: Look for ways to optimize the logic within the BAdI. This may involve reducing the number of iterations, breaking down complex operations, or using more efficient algorithms.
  Debugging: Use debugging tools to trace the execution of the BAdI and identify where the excessive steps are occurring. This can help pinpoint the exact location in the code that is causing the issue.
  Limit Data Processing: If the BAdI is processing a large dataset, consider implementing pagination or batch processing to limit the number of records processed at one time.
  Check for Other Implementations: If there are multiple BAdI implementations for the same BAdI definition, ensure that they are not interfering with each other and causing excessive processing.
  
  Related Information:
  
  BAdI Documentation: Review the official SAP documentation for the specific BAdI you are working with to understand its intended use and any limitations.
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide guidance on best practices for BAdI implementations.
  Performance Monitoring: Utilize SAP performance monitoring tools to analyze the performance of your BAdI implementation and identify bottlenecks.
  
  By following these steps, you should be able to resolve the UCT9021 error and improve the performance of your BAdI implementation.
