• What is the cause and solution for SAP error message /SOMO/JOBMON158 - Number of rows read (&1) reached or exceeded maximum (&2) ?

  The SAP error message /SOMO/JOBMON158 indicates that a job monitoring process has read a number of rows that has reached or exceeded a predefined maximum limit. This error typically occurs in the context of job monitoring or data processing within SAP systems, particularly when dealing with large datasets.
  Cause:
  
  Row Limit Exceeded: The primary cause of this error is that the number of rows processed or read by a job has exceeded the maximum limit set in the system configuration. This limit is often put in place to prevent performance issues or excessive memory usage.
  Configuration Settings: The maximum number of rows that can be read may be configured in the job monitoring settings or in the specific program that is being executed.
  Data Volume: The volume of data being processed may be unexpectedly high, leading to the limit being reached.
  
  Solution:
  
  
  Increase the Maximum Row Limit:
  
  If you have access to the configuration settings, consider increasing the maximum number of rows that can be read. This can usually be done in the job monitoring settings or the relevant program configuration.
  Consult with your SAP Basis or system administrator to make these changes.
  
  
  
  Optimize Data Processing:
  
  Review the job or program logic to see if it can be optimized to handle data in smaller chunks or batches, thereby reducing the number of rows processed at one time.
  Implement pagination or filtering to limit the number of rows being processed in a single job run.
  
  
  
  Check for Data Issues:
  
  Investigate if there are any data quality issues that are causing an unexpected increase in the number of rows. For example, duplicate records or incorrect data entries could lead to higher row counts.
  
  
  
  Monitor Job Performance:
  
  Use SAP monitoring tools to keep an eye on job performance and row counts. This can help identify trends and potential issues before they lead to errors.
