• What is the cause and solution for SAP error message VMP_MSG346 - You cannot create Planning Versioned BOM for Source Date effective BOM. ?

  SAP Error Message:
  
  VMP_MSG346: You cannot create Planning Versioned BOM for Source Date effective BOM.
  
  Cause:
  This error occurs when you try to create a Planning Versioned BOM (Bill of Materials) for a BOM that is already effective for a specific Source Date. In SAP, BOMs can be maintained with validity dates (effective dates), and planning versions are used to simulate or plan changes without affecting the current production BOM.
  The system does not allow creating a planning versioned BOM if the BOM is already date-effective (i.e., it has a source date validity). This is because planning versions are meant to be independent of date-effective BOMs, and mixing these concepts can lead to inconsistencies in planning and production.
  
  Explanation:
  
  Source Date Effective BOM: A BOM that is valid from a certain date onwards.
  Planning Versioned BOM: A BOM version used for planning purposes, independent of the production BOM's validity dates.
  
  SAP restricts creating a planning versioned BOM for a BOM that is already date-effective to avoid conflicts between planning and production data.
  
  Solution:
  
  
  Check BOM Validity:
  
  Verify if the BOM you are trying to create a planning version for has a source date validity.
  Use transaction CS03 (Display BOM) and check the validity dates.
  
  
  
  Use Correct BOM Type:
  
  If the BOM is date-effective, you should not create a planning versioned BOM for it.
  Instead, use the existing BOM with its validity dates for planning.
  
  
  
  Create Planning BOM without Source Date:
  
  If you need a planning versioned BOM, create a BOM without source date validity.
  Maintain a separate BOM for planning purposes without validity dates.
  
  
  
  Adjust Planning Version Settings:
  
  In transaction OPPR (Maintain Planning Versions), ensure that the planning version is set up correctly and does not conflict with date-effective BOMs.
  
  
  
  Consult with Production Planning Team:
  
  Align with production and planning teams to decide whether to use date-effective BOMs or planning versioned BOMs, but not both simultaneously for the same BOM.

  Transactions:
  
  CS01 - Create BOM
  CS02 - Change BOM
  CS03 - Display BOM
  OPPR - Maintain Planning Versions
  MD61 - Create Planned Independent Requirements (uses planning versions)

  Best Practices:
  
  Use date-effective BOMs for production BOM changes that are time-dependent.
  Use planning versions for simulation and what-if analysis without affecting production BOMs.
  Avoid mixing date-effective BOMs and planning versions for the same BOM to prevent planning inconsistencies.
  
  
  
  
  If you continue to face issues, consider raising a support ticket with SAP, providing details of the BOM, planning version, and the exact steps leading to the error.
