• What is the cause and solution for SAP error message WP312 - Processing function missing for segment & (function & /&) ?

  The SAP error message:
  WP312 Processing function missing for segment & (function & /&)
  typically occurs during the processing of HR infotype data, especially when dealing with HR master data or personnel actions in transaction PA30, PA40, or during batch input sessions.
  
  Cause
  
  The error indicates that the system cannot find a processing function (module or routine) assigned to a particular segment of the data being processed.
  In SAP HR, each infotype segment must have an associated processing function that handles the data input, validation, and update.
  This usually happens if:
  
  The processing function for the infotype segment is missing or not assigned in the Personnel Action (PA) or Personnel Administration (PA) customizing.
  The infotype or subtype is not properly configured in the Personnel Actions or Personnel Administration customizing.
  A custom infotype or segment is being processed but the corresponding processing function has not been implemented or linked.
  The batch input or data migration program is calling an infotype segment for which no processing function exists.
  
  
  
  
  Solution
  
  
  Check the Processing Function Assignment:
  
  Go to transaction PE04 (Personnel Actions) or PE03 (Personnel Administration) to check the processing functions assigned to the infotype segments.
  Verify that the infotype and subtype in question have a processing function assigned.
  If missing, assign the correct processing function.
  
  
  
  Verify Customizing for Personnel Actions:
  
  Use transaction SPRO ? SAP Reference IMG ? Personnel Management ? Personnel Administration ? Customizing Procedures ? Actions ? Processing of Actions.
  Check the action and the infotype segments assigned to it.
  Ensure that the processing function is maintained for each segment.
  
  
  
  Check the Infotype Configuration:
  
  Use transaction PM01 or PM02 to check infotype definitions.
  Verify that the infotype segment is active and properly configured.
  
  
  
  For Custom Infotypes or Segments:
  
  Ensure that the processing function module exists and is correctly named.
  Implement the processing function if missing.
  Assign the processing function in the customizing.
  
  
  
  Review Batch Input or Data Migration Programs:
  
  If the error occurs during batch input or data migration, check the recording or program to ensure it calls only infotypes with valid processing functions.
  Adjust the program or recording accordingly.
  
  
  
  Check for OSS Notes:
  
  Sometimes SAP releases notes related to this error for specific infotypes or HR components.
