How To Fix CONV152 - Time limit (transformation matrices) expired

SAP Error Message - Details

• Message type: E = Error

• Message class: CONV - Messages in Connection with the Converter

• Message number: 152

• Message text: Time limit (transformation matrices) expired

What causes this issue?

The waiting period for writing the transformation matrices has expired.
The following Customizing entries determine the length of these
periods:
<DS:DE.CONVERTER_MAX_WAIT_TIME>Maximum wait period for conversion
(hours)</> und <DS:DE.CONVERTER_MAX_WAIT_DAYS>Maximum wait period for
conversion (days)</>.
Parts of the BOM wherre the matrices are written were locked by another
user. For this reason not all matrices could not be written.

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?

Repeat the conversion and insure that all users release the BOMs within
the wait periods.
or
Increase the length of the wait periods.

• What is the cause and solution for SAP error message CONV152 - Time limit (transformation matrices) expired ?

  The SAP error message CONV152 indicates that a time limit has expired during the execution of a transformation, typically when converting data from one format to another (e.g., during data migration or ETL processes). This error can occur in various contexts, such as during data uploads, data transformations, or when using certain SAP tools like SAP Data Services or SAP BW.
  Causes:
  
  Long Processing Time: The transformation process is taking longer than the allowed time limit set in the system.
  Large Data Volume: The volume of data being processed is too large, causing the transformation to exceed the time limit.
  Inefficient Transformation Logic: The logic used in the transformation may not be optimized, leading to longer processing times.
  System Performance Issues: The underlying system may be experiencing performance issues, such as high CPU or memory usage, which can slow down processing.
  Configuration Settings: The time limit for transformations may be set too low in the system configuration.
  
  Solutions:
  
  
  Increase Time Limit: 
  
  You can increase the time limit for transformations in the relevant configuration settings. This can often be done in transaction codes like RSCUSTV10 for BW or other relevant settings depending on the context.
  
  
  
  Optimize Transformation Logic: 
  
  Review and optimize the transformation logic to ensure it is efficient. This may involve simplifying calculations, reducing the number of records processed at once, or breaking down the transformation into smaller, more manageable parts.
  
  
  
  Batch Processing: 
  
  If processing a large volume of data, consider breaking it into smaller batches to avoid hitting the time limit.
  
  
  
  Monitor System Performance: 
  
  Check the performance of the SAP system during the transformation process. Look for any bottlenecks in CPU, memory, or I/O that could be affecting performance.
  
  
  
  Check for Locks or Deadlocks: 
  
  Ensure that there are no locks or deadlocks in the database that could be causing delays in processing.
  
  
  
  Review Background Job Settings: 
  
  If the transformation is running as a background job, review the job settings and ensure it is scheduled during off-peak hours to minimize resource contention.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to the CONV152 error for any specific patches or updates that may address the issue.
  Transaction Codes: Familiarize yourself with relevant transaction codes for monitoring and managing data transformations, such as SM37 for job monitoring or ST22 for dumps.
  Performance Tuning: Consider engaging with SAP Basis or performance tuning experts if the issue persists, as they can provide insights into system configuration and optimization.
  
  By addressing the underlying causes and implementing the suggested solutions, you should be able to resolve the CONV152 error and improve the performance of your data transformations in SAP.
