• What is the cause and solution for SAP error message V1850 - BOM items for item & are being redetermined ?

  The SAP error message V1850 indicates that the Bill of Materials (BOM) items for a specific item are being redetermined. This typically occurs during the process of creating or processing a production order, sales order, or when performing material requirements planning (MRP). The redetermination of BOM items can happen for several reasons, and understanding the cause and solution can help resolve the issue.
  Cause:
  
  BOM Changes: The BOM for the item has been changed or updated, which triggers a redetermination of the BOM items.
  Alternative BOMs: The system may be configured to use alternative BOMs based on certain criteria (e.g., plant, production version), and the current context requires a different BOM.
  Material Master Data: Changes in the material master data, such as the status of the material or its validity period, can lead to BOM redetermination.
  Configuration Settings: The configuration settings in the system may dictate that BOMs are redetermined under certain conditions, such as during MRP runs or order creation.
  Versioning: If the BOM has multiple versions, the system may need to determine which version to use based on the current context.
  
  Solution:
  
  Check BOM Configuration: Review the BOM configuration for the item in question. Ensure that the correct BOM is active and that there are no inconsistencies.
  Review Material Master Data: Check the material master data for the item to ensure that all relevant fields are correctly filled out and that there are no issues with the material status.
  Analyze MRP Settings: If the error occurs during MRP runs, review the MRP settings and parameters to ensure they are correctly configured.
  Check for Changes: Investigate if there have been any recent changes to the BOM or material master that could have triggered the redetermination.
  Use Transaction Codes: Utilize transaction codes such as CS03 (Display BOM) or CS02 (Change BOM) to review the BOM details and ensure they are set up correctly.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on BOM redetermination and related settings.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as CS01 (Create BOM), CS02 (Change BOM), CS03 (Display BOM), and MD04 (Stock/Requirements List) for monitoring and managing BOMs and material requirements.
  SAP Notes: Check SAP Notes for any known issues or patches related to BOM redetermination errors.
  User Exits and BAdIs: If custom logic is implemented, review any user exits or Business Add-Ins (BAdIs) that may affect BOM processing.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a functional consultant who specializes in production planning and BOM management.
