  SAP Error Message: WR026 - Entry of first material missing
  Cause:
  This error typically occurs during the creation or processing of a Goods Receipt (GR) or Goods Issue (GI) document, or during the processing of a transfer posting or stock transfer in SAP MM (Materials Management) or WM (Warehouse Management) modules.
  
  The system expects the first material line item to be entered in the document, but it is missing.
  This can happen if the user tries to save or post a document without specifying any material or the first material line is left blank.
  It may also occur if the input screen or transaction requires at least one material entry and none is provided.
  
  When does it occur?
  
  During Goods Receipt or Goods Issue transactions (e.g., MIGO, MB1A, MB1B, MB1C).
  During transfer postings or stock transfers where materials must be specified.
  In warehouse management transactions where the system expects at least one material line.
  
  
  Solution:
  
  
  Enter the first material line item:
  
  Ensure that the first material is entered correctly in the document.
  Check that the material number, quantity, and other mandatory fields are filled in.
  
  
  
  Check the transaction screen:
  
  Verify that the material entry fields are not left blank.
  If using a custom screen or transaction, ensure that the material field is not suppressed or hidden.
  
  
  
  Validate data input:
  
  Make sure the material number is valid and exists in the system.
  Confirm that the quantity and other required fields are entered properly.
  
  
  
  Check for user exits or custom validations:
  
  Sometimes, custom code or user exits might enforce additional checks that cause this error.

  If using batch input or interfaces:
