• What is the cause and solution for SAP error message B1635 - Number of IDocs change pointers IDocs with the defined selection criteria ?

  The SAP error message B1635 typically indicates that the number of IDocs (Intermediate Documents) related to change pointers exceeds the defined selection criteria. This can occur in scenarios where you are trying to process or retrieve IDocs based on certain filters, and the system finds more IDocs than it is configured to handle at once.
  Cause:
  
  Exceeding Limits: The number of IDocs that match the selection criteria exceeds the maximum limit set in the system configuration.
  Selection Criteria: The selection criteria used to filter IDocs may be too broad, resulting in a large number of IDocs being selected.
  System Configuration: The system may have default settings that limit the number of IDocs processed in a single operation.
  
  Solution:
  
  Refine Selection Criteria: Narrow down the selection criteria to reduce the number of IDocs being processed. This can involve specifying more detailed filters such as date ranges, specific document types, or statuses.
  Increase Limits: If appropriate, consider increasing the limits set in the system configuration for the number of IDocs that can be processed at once. This may involve adjusting parameters in transaction codes like WE20 (Partner Profiles) or BD61 (Change Pointer Settings).
  Batch Processing: If the number of IDocs is inherently large, consider implementing batch processing to handle smaller groups of IDocs at a time.
  Monitoring and Cleanup: Regularly monitor and clean up old or unnecessary IDocs to keep the system performance optimal and reduce the number of IDocs that need to be processed.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as WE02 (Display IDoc), WE19 (Test IDoc), and BD87 (Reprocess IDocs) for managing IDocs.
