• What is the cause and solution for SAP error message SE595 - Account assignment category of requisition differs from that of PO ?

  The SAP error message SE595, which states "Account assignment category of requisition differs from that of PO," typically occurs when there is a mismatch between the account assignment categories of a purchase requisition (PR) and a purchase order (PO) in the SAP system. This can happen during the conversion of a purchase requisition into a purchase order or when trying to create a purchase order based on an existing requisition.
  Cause:
  
  
  Different Account Assignment Categories: The most common cause of this error is that the purchase requisition has a different account assignment category than the one specified in the purchase order. For example, the requisition might be set to "Cost Center" while the PO is set to "Internal Order" or "Asset."
  
  
  Manual Changes: If the account assignment category was manually changed in the purchase order after it was created from the requisition, this can lead to a mismatch.
  
  
  Configuration Issues: There may be configuration settings in the SAP system that enforce specific rules regarding account assignment categories that are not being adhered to.
  
  
  Solution:
  
  
  Check Account Assignment Categories: Review the account assignment category of both the purchase requisition and the purchase order. Ensure that they match. You can do this by:
  
  Going to the purchase requisition (ME53N) and checking the account assignment category.
  Going to the purchase order (ME23N) and checking the account assignment category.
  
  
  
  Adjust the Purchase Order: If the account assignment category of the purchase order is incorrect, you can either:
  
  Change the account assignment category in the purchase order to match that of the requisition (if applicable).
  Create a new purchase order with the correct account assignment category.
  
  
  
  Recreate the Purchase Order: If the purchase order cannot be adjusted, you may need to delete the existing purchase order and create a new one based on the requisition.
  
  
  Consult Configuration: If this issue occurs frequently, it may be worth consulting with your SAP configuration team to ensure that the settings for account assignment categories are correctly configured and aligned with your business processes.
