• What is the cause and solution for SAP error message MATSUPDEMAND_VIEW003 - Either of MRP controller or vendor is mandatory ?

  The SAP error message "MATSUPDEMAND_VIEW003: Either of MRP controller or vendor is mandatory" typically occurs in the context of Material Requirements Planning (MRP) when trying to create or update a material supply demand record. This error indicates that the system requires either an MRP controller or a vendor to be specified for the material in question, and neither has been provided.
  Cause:
  
  Missing MRP Controller: The MRP controller is responsible for managing the planning and procurement of materials. If this field is left blank, the system cannot determine who is responsible for the material.
  Missing Vendor: If the material is procured from a vendor, the vendor information must be provided. If this is missing, the system cannot identify where to source the material from.
  Configuration Issues: There may be configuration settings in the material master or MRP settings that are not set up correctly, leading to this error.
  
  Solution:
  
  
  Check Material Master Data:
  
  Go to the material master record (transaction code MM02 for change or MM03 for display).
  Ensure that either the MRP controller or vendor is filled in the relevant views (MRP view or Purchasing view).
  If the material is produced in-house, ensure the MRP controller is specified. If it is procured externally, ensure the vendor is specified.
  
  
  
  Update MRP Controller:
  
  If the MRP controller is missing, you can assign one by editing the material master record in the MRP view.
  Ensure that the MRP controller exists in the system and is active.
  
  
  
  Update Vendor Information:
  
  If the material is sourced from a vendor, ensure that the vendor is assigned in the Purchasing view of the material master.
  Check if the vendor is active and has valid purchasing information.
  
  
  
  Review Configuration:
  
  If the issue persists, review the configuration settings in the MRP and Purchasing areas to ensure they are set up correctly.
  Consult with your SAP configuration team if necessary.
  
  
  
  Check for User Exits or BAdIs:
  
  If there are any custom developments (user exits or BAdIs) that might be affecting the MRP or vendor assignment, review those as well.

  Vendor Master Data: Ensure that vendor master records are maintained properly in transaction code XK01 (Create Vendor) or XK02 (Change Vendor).
  
  By ensuring that either the MRP controller or vendor is specified in the material master, you should be able to resolve the error message MATSUPDEMAND_VIEW003.
