• What is the cause and solution for SAP error message MPE_PLAN_EXEC026 - Date effective BOM with phantom assembly is not supported ?

  The SAP error message MPE_PLAN_EXEC026 indicates that there is an issue with the Bill of Materials (BOM) when trying to execute a planning or production process involving a phantom assembly. A phantom assembly is a type of assembly that is not physically stocked but is used in the production process to simplify the BOM structure.
  Cause:
  The error typically arises due to the following reasons:
  
  
  Date-Effective BOM: The BOM being used is date-effective, meaning it has validity periods defined for its components. This can lead to complications when trying to process phantom assemblies, as the system may not be able to determine the correct components to use based on the date.
  
  
  Phantom Assembly Configuration: The configuration of the phantom assembly in the BOM may not be set up correctly, or the system may not support the combination of date-effective BOMs with phantom assemblies.
  
  
  Planning Parameters: The planning parameters or settings in the system may not be compatible with the use of phantom assemblies in conjunction with date-effective BOMs.
  
  
  Solution:
  To resolve the error, consider the following steps:
  
  
  Check BOM Configuration:
  
  Review the BOM for the phantom assembly to ensure it is correctly configured. Make sure that the components are properly defined and that the phantom assembly is set up as intended.
  
  
  
  Review Date-Effective BOM Settings:
  
  Check the validity dates of the BOM components. Ensure that the date-effective BOM is valid for the date on which you are trying to execute the planning or production process.
  
  
  
  Use Standard BOM:
  
  If possible, consider using a standard BOM instead of a date-effective BOM for the phantom assembly. This may help bypass the limitations associated with date-effective BOMs.
  
  
  
  Consult SAP Documentation:
  
  Refer to SAP documentation or notes related to BOMs and phantom assemblies. There may be specific guidelines or limitations documented that can provide further insights.
  
  
  
  System Configuration:
  
  Check the system configuration settings related to BOM processing and planning. Ensure that the settings allow for the use of phantom assemblies with date-effective BOMs, if applicable.
  
  
  
  Contact SAP Support:
  
  If the issue persists, consider reaching out to SAP support for assistance. They may provide specific patches or updates that address this issue.
  
  
  
  Related Information:
  
  Phantom Assemblies: Understand the concept of phantom assemblies in SAP and how they are used in BOMs.
  BOM Types: Familiarize yourself with different types of BOMs in SAP, including standard BOMs, variant BOMs, and date-effective BOMs.
  Planning Processes: Review the planning processes in SAP, including MRP (Material Requirements Planning) and how BOMs are utilized in these processes.
  
  By following these steps and understanding the underlying concepts, you should be able to address the error message MPE_PLAN_EXEC026 effectively.
