• What is the cause and solution for SAP error message CPWB412 - Do not enter an alternative, if you want to copy more than one BOM header ?

  The SAP error message CPWB412 typically occurs in the context of copying Bill of Materials (BOM) in the SAP system, particularly when using the BOM copy function in the transaction code CPWB (BOM Workbench). This error indicates that you are trying to copy multiple BOM headers while also specifying an alternative BOM, which is not allowed.
  Cause:
  The error arises when:
  
  You attempt to copy more than one BOM header (i.e., multiple BOMs) and at the same time specify an alternative BOM.
  The system does not support copying multiple BOMs with an alternative BOM because it can lead to ambiguity in the data being copied.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Copy One BOM at a Time: If you need to copy BOMs with an alternative, ensure that you are only copying one BOM header at a time. This means selecting a single BOM for copying without trying to include multiple BOMs in the selection.
  
  
  Remove Alternative BOM Specification: If you need to copy multiple BOMs, do not specify an alternative BOM. Just proceed with the copying of the BOM headers without any alternatives.
  
  
  Check BOM Selection: Ensure that your selection criteria for BOMs are correct and that you are not inadvertently selecting multiple BOMs when you intend to copy just one.
  
  
  Review Documentation: Consult the SAP documentation or help files related to BOM management and the CPWB transaction for any additional guidelines or restrictions regarding copying BOMs.
  
  
  Related Information:
  
  Transaction Codes: CPWB (BOM Workbench), CS01 (Create BOM), CS02 (Change BOM), CS03 (Display BOM).
  BOM Types: Understand the different types of BOMs (e.g., production BOM, sales BOM, etc.) and how they relate to alternatives.
  SAP Notes: Check for any relevant SAP Notes that might address specific issues or enhancements related to BOM copying.
  
  If the problem persists after following these steps, it may be beneficial to consult with your SAP support team or refer to SAP community forums for further assistance.
