Smart SAP Assistant

• What is the cause and solution for SAP error message MEPO841 - PO history already exists (Multiple account assignment not possible) ?

  The SAP error message MEPO841 ("PO history already exists (Multiple account assignment not possible)") typically occurs when you are trying to create or modify a Purchase Order (PO) that has multiple account assignments, but there is already existing history for that PO. This situation arises when the system detects that the PO has already been processed in a way that does not allow for multiple account assignments.
  Cause:
  
  Existing History: The PO has already been processed (e.g., goods receipt, invoice receipt) which creates a history that is incompatible with multiple account assignments.
  Account Assignment Type: The PO may have been created with a specific account assignment type (like cost center, internal order, etc.) that does not support multiple account assignments.
  Document Type Restrictions: Certain document types in SAP may have restrictions on how account assignments can be handled.
  
  Solution:
  
  Check PO History: Review the history of the Purchase Order to see if there are any goods receipts or invoices that have already been posted. If there is history, you may need to create a new PO instead of modifying the existing one.
  Change Account Assignment: If the PO is still in a draft state and has not been processed, you can try to change the account assignment type to one that allows multiple assignments, if applicable.
  Create a New PO: If the existing PO has history that cannot be changed, consider creating a new Purchase Order with the desired account assignments.
  Consult Documentation: Review SAP documentation or consult with your SAP support team to understand the specific configurations and restrictions related to your organization's use of account assignments in POs.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like ME23N (Display Purchase Order) to view the PO history and details.
