• What is the cause and solution for SAP error message COCM408 - Error during deletion: Data inconsistency in RESB, VSRESB_CN and COMPCMP ?

  The SAP error message COCM408 indicates that there is a data inconsistency in the tables RESB (Reservation/dependent requirements), VSRESB_CN (View for Reservation), and COMPCMP (Component Comparison). This error typically occurs when you attempt to delete a reservation or dependent requirement, but the system finds inconsistencies in the related data.
  Causes:
  
  
  Data Inconsistency: The most common cause is that the data in the RESB table does not match the expected data in the VSRESB_CN and COMPCMP tables. This can happen due to:
  
  Manual changes to the database that bypassed standard SAP processes.
  Incomplete or failed transactions that left orphaned records.
  Issues during data migration or system upgrades.
  
  
  
  Locked Entries: Sometimes, if the entries are locked by another process or user, it can lead to inconsistencies.
  
  
  Custom Development: Custom programs or enhancements that manipulate these tables may inadvertently cause inconsistencies.
  
  
  Solutions:
  
  
  Check Data Consistency:
  
  Use transaction codes like SE11 or SE16 to check the contents of the RESB, VSRESB_CN, and COMPCMP tables for inconsistencies.
  Look for entries that should not exist or are missing.
  
  
  
  Repair Inconsistencies:
  
  If you identify specific inconsistencies, you may need to manually correct or delete the problematic entries. This should be done with caution and ideally in a test environment first.
  Use transaction code SE14 (Database Utility) to check and repair inconsistencies in the database.
  
  
  
  Use Standard SAP Transactions:
  
  If the error occurs during a specific transaction, try to use the standard SAP transaction to delete the reservation or dependent requirement instead of custom programs.
  
  
  
  Check for Locks:
  
  Use transaction SM12 to check for any locks on the relevant entries. If there are locks, you may need to wait for them to be released or contact the user who has locked the entries.
