• What is the cause and solution for SAP error message WS151 - Supplier &1 posted with reconciliation account &2 and posting key &3 ?

  Certainly! Here's a detailed explanation for the SAP error message WS151:
  
  SAP Error Message: WS151
  Text: Supplier &1 posted with reconciliation account &2 and posting key &3
  
  Cause:
  This error occurs during the posting of a vendor (supplier) invoice or credit memo when the system detects that the reconciliation account assigned to the vendor master record does not match the reconciliation account used in the line item posting.
  
  Supplier &1: Vendor number involved in the posting.
  Reconciliation account &2: The reconciliation account assigned to the vendor master record.
  Posting key &3: The posting key used in the line item (e.g., 31 for vendor invoice, 21 for vendor credit memo).
  
  The mismatch means that the posting is trying to use a reconciliation account different from the one assigned to the vendor master record, which is not allowed because the reconciliation account is a control account that links vendor transactions to the general ledger.
  
  Why does this happen?
  
  The vendor master record has a specific reconciliation account assigned in the vendor master data (transaction FK03 or XK03).
  The posting document line item is using a different reconciliation account, either because:
  
  The posting was manually overridden.
  The account determination configuration is incorrect.
  The document was created via an interface or upload with incorrect data.
  The vendor master data is inconsistent or incorrectly maintained.
  
  
  
  
  Solution:
  
  
  Check Vendor Master Data:
  
  Use transaction XK03 or FK03 to display the vendor master record.
  Go to the Accounting view and verify the reconciliation account assigned.
  
  
  
  Check the Posting Document:
  
  Review the document or posting that triggered the error.
  Identify the reconciliation account used in the line item.
  
  
  
  Correct the Posting:
  
  Ensure that the posting uses the reconciliation account assigned to the vendor master.
  If posting manually, do not override the reconciliation account.
  If posting via interface or upload, correct the data source to use the correct reconciliation account.
  
  
  
  Adjust Vendor Master if Needed:
  
  If the vendor master reconciliation account is incorrect, update it using XK02 or FK02.
  Be cautious when changing reconciliation accounts as it affects financial reporting.
  
  
  
  Check Account Determination:
  
  Verify the automatic account determination settings in OBYC or related configuration to ensure correct reconciliation accounts are assigned.
  
  
  
  
  Additional Information:
  
  The reconciliation account is a GL control account that links vendor transactions to the general ledger.
  Posting to a different reconciliation account than the one assigned to the vendor master is not allowed because it breaks the link between vendor sub-ledger and general ledger.
  This error helps maintain data integrity and consistency in financial postings.
  Posting keys define the type of posting (debit/credit, vendor/customer, etc.) and must be consistent with the reconciliation account.
