  SAP Error Message:
  
  WG337 - Unknown material used for selection. Please re-enter material.
  
  Cause:
  This error occurs when a material number entered in a selection screen or transaction is not recognized by the system. The material may not exist in the material master data, or it might be incorrectly entered (typo, wrong material number, or missing leading zeros). Essentially, SAP cannot find the material in the database to proceed with the requested operation.
  
  Common Scenarios:
  
  Entering a material number that has not been created or maintained in the system.
  Using an incorrect or invalid material number in reports, transactions, or selection screens.
  Material master data is incomplete or not properly extended to the relevant plant or sales organization.
  Typographical errors or wrong material number format.
  
  
  Solution:
  
  
  Verify Material Number:
  
  Check the material number entered for correctness.
  Ensure there are no typos or missing characters.
  Confirm the material number exists in the system (use transaction MM03 to display material master).
  
  
  
  Check Material Master Data:
  
  If the material does not exist, create it using MM01.
  If the material exists but is not extended to the relevant plant or sales area, extend it using MM01 or MM02.
  
  
  
  Use Correct Material Number Format:
  
  Ensure the material number is entered in the correct format (leading zeros if applicable).
  Use the search help (F4) to select the material to avoid manual entry errors.
  
  
  
  Check Authorizations:
  
  Ensure the user has authorization to view or use the material in the relevant plant or sales area.
  
  
  
  Re-enter Material:
  
  After verifying and correcting the material number, re-enter it in the selection screen or transaction.
  
  
  
  
  Additional Information:
  
  This message is a standard SAP message related to material master validation.
  It is often encountered in logistics modules such as MM (Materials Management), SD (Sales and Distribution), and PP (Production Planning).
  If the material is newly created, ensure that all necessary views and organizational levels are maintained.
  If the error persists despite correct material entry, check for custom validations or user-exits that might restrict material usage.
