Smart SAP Assistant

• What is the cause and solution for SAP error message CNV20551699 - MATNR &1 is excluded from deletion;Its associated to active BOM(STLNR) &2 ?

  The SAP error message CNV20551699 indicates that a material (MATNR) cannot be deleted because it is associated with an active Bill of Materials (BOM) (STLNR). This is a common issue when trying to delete materials that are still linked to other objects in the system.
  Cause:
  The error occurs because the material you are trying to delete is still referenced in an active BOM. SAP enforces data integrity, so it prevents the deletion of materials that are still in use. This is to ensure that there are no broken links or inconsistencies in the data.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check BOM Associations:
  
  Use transaction code CS03 (Display BOM) to check if the material is indeed associated with an active BOM.
  Enter the material number (MATNR) and check the BOM list to see which BOM it is linked to.
  
  
  
  Deactivate or Delete the BOM:
  
  If the BOM is no longer needed, you can deactivate or delete it. Use transaction code CS02 (Change BOM) to make changes to the BOM.
  If you want to delete the BOM, ensure that it is not being used in any production orders or other processes.
  
  
  
  Remove Material from BOM:
  
  If you still need the BOM but want to delete the material, you can remove the material from the BOM using transaction code CS02.
  
  
  
  Check for Other Dependencies:
  
  Ensure that there are no other dependencies or references to the material in other areas of the system, such as production orders, purchase orders, or inventory records.
  
  
  
  Retry Deletion:
  
  Once you have either deleted or modified the BOM, you can attempt to delete the material again using transaction code MM06 (Change Material).
  
  
  
  Related Information:
  
  Transaction Codes:
  
  CS03: Display BOM
  CS02: Change BOM
  MM06: Change Material
  
  
  BOM Structure: Understanding the structure of BOMs and how materials are linked can help in managing materials effectively.
  Data Integrity: SAP maintains strict data integrity rules, which is why it prevents the deletion of materials that are still in use.
  
  If you continue to face issues after following these steps, it may be helpful to consult with your SAP administrator or support team for further assistance.
