  Error Message
  VMP_MSG351: Plant and Usage are mandatory.
  
  Cause
  This error occurs in SAP when you are trying to maintain or process a material master, batch, or related data in the Variant Configuration (LO-VC) or in the context of a process where Plant and Usage fields are required but have not been entered.
  
  Plant: The organizational unit within a company where the material is stored or produced.
  Usage: Specifies the purpose or context in which the material or batch is used (e.g., sales, production, quality inspection).
  
  In many SAP transactions related to batch management, variant configuration, or material master data, the system requires both Plant and Usage to determine the correct data records, such as batch characteristics, classification, or configuration profiles.
  
  When does it typically occur?
  
  When creating or changing batch characteristics or classification data.
  When working with variant configuration and the system needs to identify the correct plant-specific or usage-specific data.
  During sales order processing or production order creation if batch determination or classification is involved.
  When maintaining material master views that require plant and usage information.
  
  
  Solution
  
  
  Enter Plant and Usage:
  
  Ensure that the Plant field is filled with the correct plant code.
  Ensure that the Usage field is filled with the appropriate usage value.
  
  
  
  Check the transaction screen:
  
  Look for the fields Plant and Usage in the screen or tab where the error occurs.
  If these fields are missing, check if the screen variant or user parameters are hiding them.
  
  
  
  Verify Customizing:
  
  Check if the plant and usage are correctly maintained in the customizing settings related to batch management, variant configuration, or classification.
  For example, in SPRO ? Logistics General ? Batch Management ? Basic Settings ? Define Usage for Batch Classification, ensure that the usage values are defined and assigned properly.
  
  
  
  Check Material Master Data:
  
  Verify that the material master has the plant assigned.
  Check if the material is extended to the plant in question.
  
  
  
  Check User Exits or Enhancements:
  
  Sometimes, custom code or user exits might enforce mandatory fields. Verify if any custom logic is causing the error.
