Smart SAP Assistant

• What is the cause and solution for SAP error message FCO_SFIN034 - &1 line items in table COEP with empty field POSNR (type 'COBK') ?

  The SAP error message FCO_SFIN034 indicates that there are line items in the COEP table (which stores CO document line items) that have an empty field for the position number (POSNR) in the COBK table (which stores CO document header data). This situation can lead to inconsistencies in the data and may prevent certain financial operations from being completed successfully.
  Cause:
  
  
  Data Inconsistency: The primary cause of this error is data inconsistency where line items in COEP do not have a corresponding position number in the COBK table. This can happen due to:
  
  Manual data entry errors.
  Issues during data migration or system upgrades.
  Incomplete or failed postings in the Controlling (CO) module.
  
  
  
  Custom Development: If there are custom programs or enhancements that manipulate CO documents, they may inadvertently create entries in COEP without properly populating the POSNR field.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Identify the Affected Entries:
  
  Use transaction SE16 or SE16N to query the COEP table and identify the entries with an empty POSNR field.
  You can run a query like:
  SELECT * FROM COEP WHERE POSNR IS NULL.
  
  
  
  
  Analyze the Data:
  
  Check the related entries in the COBK table to understand why the POSNR is missing.
  Look for any patterns or specific transactions that may have caused this issue.
  
  
  
  Correct the Data:
  
  If the entries are incorrect, you may need to delete or correct them. This can be done using transaction codes like FB08 (to reverse documents) or through custom programs if necessary.
  Ensure that any corrections maintain data integrity and do not affect other financial reports.
  
  
  
  Check for Custom Code:
  
  Review any custom developments that interact with CO documents to ensure they are functioning correctly and not causing this issue.
  
  
  
  Consult SAP Notes:
  
  Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide guidance on how to handle it.
  
  
  
  Testing:
  
  After making corrections, perform thorough testing to ensure that the issue is resolved and that no new inconsistencies are introduced.
  
  
  
  Related Information:
  
  COEP Table: Contains line items for CO documents, including cost center accounting, internal orders, and other controlling-related postings.
  COBK Table: Contains header data for CO documents, including document number, fiscal year, and other key identifiers.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  SE16/SE16N: Data browser for table queries.
  FB08: Reverse document.
  KSB1: Display actual line items for cost centers.
  
  
  
  If the issue persists after following these steps, it may be beneficial to engage with SAP support or a consultant who specializes in SAP Controlling for further assistance.
