• What is the cause and solution for SAP error message MD358 - The creation of subcontracting MRP areas is not supported ?

  The SAP error message MD358, which states "The creation of subcontracting MRP areas is not supported," typically occurs in the context of Material Requirements Planning (MRP) when trying to create or manage MRP areas for subcontracting scenarios. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  MRP Area Configuration: The error usually arises when there is an attempt to create an MRP area for a subcontracting process, which is not supported by the system. In SAP, subcontracting is treated differently than standard MRP areas.
  Material Master Settings: The material master record may not be configured correctly for subcontracting. If the material is not set up to allow subcontracting, this error can occur.
  MRP Type: The MRP type assigned to the material may not be compatible with subcontracting processes.
  System Limitations: Certain versions or configurations of SAP may have limitations regarding the use of MRP areas with subcontracting.
  
  Solution:
  
  Check MRP Area Settings: Review the configuration of MRP areas in your system. Ensure that you are not trying to create an MRP area specifically for subcontracting.
  Material Master Configuration: Verify the material master settings for the relevant materials. Ensure that the material is set up for subcontracting and that the appropriate MRP type is assigned.
  Use Standard MRP: Instead of creating MRP areas for subcontracting, consider using standard MRP processes. Subcontracting can be managed through standard MRP without the need for specific MRP areas.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on managing subcontracting in your version of SAP.
  SAP Notes: Check for any relevant SAP Notes that may address this issue. Sometimes, there are patches or updates that can resolve specific errors.
  Contact SAP Support: If the issue persists, consider reaching out to SAP support for assistance, especially if you suspect it may be a bug or limitation in your current SAP version.
  
  Related Information:
  
  Subcontracting in SAP: Understand how subcontracting works in SAP, including the use of purchase orders and the integration with MRP.
  MRP Types: Familiarize yourself with different MRP types and their implications for material planning.
  SAP Community: Engage with the SAP Community forums to see if other users have encountered similar issues and what solutions they have found.
  Training and Documentation: Consider training sessions or documentation on MRP and subcontracting processes in SAP to enhance understanding and prevent similar issues in the future.
  
  By addressing the configuration and understanding the limitations of MRP areas in subcontracting, you can resolve the MD358 error effectively.
