Smart SAP Assistant

• What is the cause and solution for SAP error message /PLMI/GSS_B2B012 - BOM item &1 valid-from date &2 is before BOM header &3 valid-from date &4 ?

  The SAP error message /PLMI/GSS_B2B012 indicates that there is a discrepancy between the valid-from dates of a Bill of Materials (BOM) item and the BOM header. Specifically, the valid-from date of the BOM item is earlier than the valid-from date of the BOM header. This can lead to issues in the system as it violates the expected chronological order of the BOM data.
  Cause:
  
  Date Mismatch: The BOM item has a valid-from date that is set before the valid-from date of the BOM header. This can happen due to incorrect data entry or updates made to the BOM item or header.
  Data Migration Issues: If data was migrated from another system or if there were bulk updates, it’s possible that the dates were not aligned correctly.
  Manual Changes: Users may have manually changed the valid-from dates without ensuring that the BOM item dates are consistent with the BOM header.
  
  Solution:
  
  
  Check BOM Header and Item Dates:
  
  Go to the BOM in the SAP system and check the valid-from date of the BOM header.
  Compare it with the valid-from date of the BOM item that is causing the error.
  
  
  
  Adjust Dates:
  
  If the BOM item’s valid-from date is indeed earlier than the BOM header’s date, you will need to adjust the BOM item’s valid-from date to be the same as or later than the BOM header’s valid-from date.
  This can be done through the BOM maintenance transaction (e.g., CS02 for changing BOMs).
  
  
  
  Consistency Check:
  
  After making the changes, perform a consistency check to ensure that all BOM items are aligned with the BOM header dates.
  
  
  
  Review Change Logs:
  
  If the issue persists, review the change logs to identify who made the changes and when, to prevent future occurrences.
  
  
  
  Consult Documentation:
  
  If you are unsure about the changes, consult SAP documentation or reach out to your SAP support team for guidance.
  
  
  
  Related Information:
  
  BOM Structure: Understanding the structure of BOMs in SAP is crucial. The BOM header contains general information, while the items contain specific components and their valid dates.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), and CS03 (Display BOM).
  SAP Notes: Check for any SAP Notes related to BOM management that might address similar issues or provide additional guidance.
  
  By following these steps, you should be able to resolve the error and ensure that your BOM data is consistent and accurate.
