• What is the cause and solution for SAP error message APPL_MM_PUR_OA_CON021 - Multiple accounts cannot be added ?

  The SAP error message APPL_MM_PUR_OA_CON021 indicates that multiple accounts cannot be added in a specific context, typically related to account assignment in purchasing documents or materials management. This error often arises when trying to assign multiple accounts to a single line item in a purchase order, invoice, or similar document where the system expects only one account assignment.
  Cause:
  
  Multiple Account Assignments: The primary cause of this error is the attempt to assign more than one account to a single line item. In SAP, certain transactions or document types only allow a single account assignment per line item.
  Configuration Settings: The system configuration may restrict the number of account assignments based on the document type or the settings in the relevant configuration (e.g., account assignment categories).
  Document Type Restrictions: Some document types may inherently support only single account assignments due to their nature (e.g., standard purchase orders vs. service purchase orders).
  
  Solution:
  
  Review Account Assignments: Check the line item in the document where the error occurred. Ensure that only one account is assigned to that line item. If multiple accounts are needed, consider splitting the line items into separate entries.
  Adjust Document Structure: If the business process requires multiple accounts, consider restructuring the document to accommodate this. For example, create multiple line items for the same material or service, each with its own account assignment.
  Configuration Review: If you believe that the configuration should allow multiple account assignments, consult with your SAP configuration team to review the settings for the relevant document types and account assignment categories.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on account assignments for the document type you are working with.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as ME21N (Create Purchase Order), ME22N (Change Purchase Order), or MIRO (Enter Incoming Invoice) where this error might occur.
