• What is the cause and solution for SAP error message LATP100 - Change ATP confirmation only after check in the same transaction ?

  The SAP error message LATP100 ("Change ATP confirmation only after check in the same transaction") typically occurs in the context of Advanced Available-to-Promise (ATP) checks in SAP. This error indicates that there is an attempt to change an ATP confirmation after the ATP check has already been performed in the same transaction. 
  
  Cause:
  
  ATP Check Sequence: The ATP check is designed to ensure that stock availability is confirmed before any changes are made to the confirmation. If the system has already performed an ATP check, it expects that any changes to the confirmation should be done in a separate transaction.
  Transaction Logic: The logic of the transaction does not allow for modifications to the ATP confirmation once the check has been executed. This is to maintain data integrity and ensure that the availability status is accurate.
  
  
  Solution:
  
  Separate Transactions: If you need to change the ATP confirmation, you should first complete the current transaction
