  SAP Error Message:
  WSAM_SHMAE020: Material &1 not maintained in the plants of your plant selection
  
  Cause:
  This error occurs when you try to perform an operation (such as creating or processing a sales order, delivery, or any transaction involving materials) and the material you are referencing is not maintained or extended in any of the plants included in your current plant selection or user-specific plant authorization.
  In other words, the system checks whether the material exists and is valid in the plants you are allowed to work with. If the material master data is not extended to any of these plants, the system throws this error.
  
  Explanation:
  
  Material Master Data in SAP is maintained per plant. A material can be extended to multiple plants, but it must be extended to at least one plant that is within your plant selection or authorization.
  Your plant selection might be restricted by user roles or default settings.
  If the material is not extended to any of these plants, the system cannot process transactions involving that material for your user.
  
  
  Solution:
  
  
  Check Material Master Extension:
  
  Use transaction MM03 (Display Material) and check the plant data views.
  Verify if the material is extended to the plants you are authorized to work with.
  
  
  
  Extend Material to Required Plants:
  
  If the material is not extended to the required plant(s), extend it using transaction MM01 (Create Material) or MM02 (Change Material).
  During extension, select the relevant plant(s) and maintain the necessary data views (e.g., MRP, Work Scheduling, Sales, etc.).
  
  
  
  Check User Plant Selection/Authorization:
  
  Verify your user master record or plant selection parameters.
  Ensure you have authorization for the plants where the material is extended.
  If necessary, request your SAP security team to update your plant authorizations.
  
  
  
  Adjust Plant Selection:
  
  If your plant selection is too restrictive, adjust it to include plants where the material is maintained.
  This can be done via user parameters or selection screens depending on the transaction.
  
  
  
  
  Related Information:
  
  
  Transaction Codes:
  
  MM01 – Create Material
  MM02 – Change Material
  MM03 – Display Material
  MMBE – Stock Overview (to check stock per plant)
  SU01 – User maintenance (to check user authorizations)
  
  
  
  Tables:
  
  MARA – General Material Data
  MARC – Plant Data for Material (shows which plants the material is extended to)
  
  
  
  Notes:
  
  Always ensure that the material master is properly maintained for all plants involved in your business process.
  Plant-specific data includes procurement, MRP, storage, and sales data, so missing plant extension can cause various errors.
