• What is the cause and solution for SAP error message WU148 - Only a plant-specific supplier can be assigned to mat. & & in plant & ?

  The SAP error message WU148 indicates that there is an issue with assigning a supplier to a material in a specific plant. This error typically arises when you attempt to assign a vendor (supplier) to a material that is not set up as a plant-specific supplier in the system. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Plant-Specific Vendor Requirement: The material you are trying to assign a supplier to is configured to require a plant-specific vendor. This means that the vendor must be specifically assigned to that plant for the material.
  Vendor Master Data: The vendor you are trying to assign may not have been set up correctly in the vendor master data for that specific plant.
  Material Master Data: The material may not be configured to allow for a non-plant-specific vendor.
  
  Solution:
  
  
  Check Vendor Master Data:
  
  Go to the vendor master data (transaction code XK03 or MK03).
  Verify that the vendor is set up for the specific plant you are trying to assign it to. You should see a plant-specific view for the vendor.
  If the vendor is not set up for that plant, you will need to create or extend the vendor for that specific plant using transaction code XK01 or MK01.
  
  
  
  Check Material Master Data:
  
  Go to the material master data (transaction code MM03).
  Check the purchasing view for the material and ensure that it is set up to allow for plant-specific vendors.
  If necessary, you may need to adjust the material master data to allow for the assignment of a plant-specific vendor.
  
  
  
  Assign Vendor to Material:
  
  Once the vendor is confirmed to be set up for the specific plant, you can proceed to assign the vendor to the material using transaction code ME11 (Create Purchasing Info Record) or ME12 (Change Purchasing Info Record).
  
  
  
  Consult with Your SAP Administrator: If you are unsure about the setup or if you do not have the necessary permissions to make changes, consult with your SAP administrator or the person responsible for vendor and material master data management in your organization.
