• What is the cause and solution for SAP error message WRPLCHK002 - Enter package size for parallel processing ?

  SAP Error Message:
  
  WRPLCHK002 - Enter package size for parallel processing
  
  Cause:
  This error occurs when you are trying to execute a process or job in SAP that supports parallel processing, but the system requires you to specify the package size (i.e., the number of records or units to be processed in each parallel batch) and it has not been entered.
  In many SAP programs or transactions that handle large data volumes, parallel processing is used to improve performance by splitting the workload into smaller chunks (packages). The system needs the package size to know how to divide the data.
  
  When does it occur?
  
  During execution of batch jobs or background programs that support parallel processing.
  When running certain data load, data transfer, or mass processing transactions.
  When the program or transaction expects a package size parameter but it is left blank or zero.
  
  
  Solution:
  
  
  Enter the Package Size:
  
  When prompted by the message WRPLCHK002, enter a valid package size value.
  The package size is typically a positive integer representing the number of records per parallel process.
  Example: If you have 10,000 records and enter a package size of 1,000, the system will create 10 parallel processes.
  
  
  
  Check Default Values:
  
  Some transactions or programs allow you to set a default package size in their selection screen or configuration.
  Review the program documentation or selection screen for a field like "Package Size," "Batch Size," or "Number of Records per Job."
  
  
  
  Adjust Package Size According to System Capacity:
  
  Choose a package size that balances performance and system load.
  Too small package size may create too many parallel jobs, increasing overhead.
  Too large package size may reduce parallelism and increase runtime.
  
  
  
  Consult Program Documentation:
  
  Some SAP standard programs or custom developments have specific recommendations for package size.
  Check SAP notes or program documentation for suggested values.
  
  
  
  
  Related Information:
  
  
  Parallel Processing in SAP:
  
  SAP uses parallel processing to improve performance by dividing large data sets into smaller chunks processed simultaneously.
  
  
  Package Size Parameter:
  
  This parameter controls the granularity of parallel processing.
  
  
  Transaction Examples:  
  
  Data migration tools (e.g., LSMW, BDC sessions)  
  Mass processing transactions (e.g., mass changes, mass updates)  
  Background jobs with parallelization options
  
  
  
  SAP Notes:
  
  If the error persists or the package size field is not visible, check for relevant SAP Notes or OSS messages related to the specific program or transaction you are using.
  
  
  
  Summary:
  
  Cause: Package size for parallel processing not entered.
  Solution: Enter a valid package size (number of records per parallel batch) when prompted.
  Tip: Adjust package size based on system performance and workload.
