    SAP Error Message: W4806 - LIA document still exists

    Message Text:
    LIA document still exists


    Cause

    This warning message typically occurs in the context of Logistics Invoice Verification (LIV) or Logistics Invoice Adjustment (LIA) processes in SAP MM (Materials Management).

    • The system detects that an LIA document (Logistics Invoice Adjustment document) related to a particular invoice or delivery still exists in the system.
    • This usually means that an invoice or credit memo has been partially or fully adjusted, but the adjustment document has not been cleared or processed completely.
    • The presence of an open LIA document prevents certain subsequent actions, such as posting a new invoice or clearing the existing one.
    • It can also occur if you try to cancel or reverse an invoice while an LIA document is still active.

    When does it occur?

    • During invoice verification or invoice posting.
    • When trying to post a new invoice or credit memo against a purchase order or delivery that already has an open LIA document.
    • When attempting to cancel or reverse an invoice that has an associated LIA document still open.

    Solution

    1. Check for Open LIA Documents:

      • Use transaction MRBR (Release Blocked Invoices) or MRRL (Evaluate Invoice Blocks) to check if there are any blocked or open LIA documents.
      • Alternatively, check the invoice document flow or related documents to identify the LIA document.
    2. Clear or Process the LIA Document:

      • If the LIA document is still open, process it completely by posting the necessary credit or debit adjustments.
      • If the LIA document is no longer needed, consider reversing or deleting it if business processes allow.
    3. Invoice Cancellation:

      • If you are trying to cancel an invoice, first ensure that all related LIA documents are cleared or reversed.
      • Use transaction MR8M (Cancel Invoice Document) carefully after ensuring no open LIA documents exist.
    4. Consult Document Flow:

      • Check the document flow in the purchase order or delivery to understand the relationship between the invoice and LIA documents.
      • Use transaction ME23N (Display Purchase Order) and navigate to the invoice documents.
    5. SAP Notes and Support:

      • Check for any relevant SAP Notes that might address specific scenarios or bugs related to LIA documents.
      • If the problem persists, consider raising a support ticket with SAP, providing the invoice number, LIA document number, and system logs.
