• What is the cause and solution for SAP error message FINS_RECON336 - &1: Open item in BSEG, missing in BSIK_BCK (but available in BSAK_BCK) ?

  The SAP error message FINS_RECON336 indicates that there is an inconsistency in the reconciliation of open items in the accounting documents. Specifically, it points out that there is an open item in the BSEG table (which contains line item data for accounting documents) that is missing in the BSIK_BCK table (which is used for open items related to vendor accounts) but is available in the BSAK_BCK table (which contains cleared items for vendor accounts).
  Cause:
  The error typically arises due to one of the following reasons:
  
  Data Inconsistency: There may be inconsistencies in the data between the BSEG and BSIK_BCK tables, possibly due to incomplete postings, incorrect clearing, or issues during data migration.
  Clearing Issues: The open item may have been cleared in a way that did not properly update the BSIK_BCK table.
  Custom Developments: If there are custom programs or enhancements that manipulate accounting data, they may not be correctly handling the updates to the BSIK_BCK table.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Open Item: Identify the specific open item causing the issue. You can do this by using transaction codes like FB03 (Display Document) to view the details of the document in BSEG.
  
  
  Reconcile Data: 
  
  Use transaction FBL1N (Vendor Line Item Display) to check the status of the vendor account and see if the open item is reflected correctly.
  Compare the entries in BSEG, BSIK_BCK, and BSAK_BCK to identify discrepancies.
  
  
  
  Run Consistency Checks: 
  
  Use transaction SARA to run archiving and consistency checks for the relevant tables.
  You can also use transaction S1 (SAP Note Assistant) to check for any relevant SAP Notes that may address this issue.
  
  
  
  Manual Correction: If the issue is due to a specific document that has not been cleared properly, you may need to manually clear the item or adjust the entries to ensure that they are consistent across the relevant tables.
  
  
  Consult SAP Support: If the issue persists and you cannot identify the root cause, consider reaching out to SAP Support for assistance. They may provide specific guidance based on the version of SAP you are using and any known issues.
