• What is the cause and solution for SAP error message WT002 - Please enter either a material group or a material ?

  SAP Error Message:
  
  WT002 – Please enter either a material group or a material
  
  Cause:
  This error occurs in SAP when a transaction or report requires you to specify either a Material Group or a Material Number, but neither has been entered. The system expects at least one of these fields to be filled to proceed with the processing or selection.
  Typically, this happens in scenarios such as:
  
  When running reports or selection screens related to inventory, materials management, or warehouse management.
  When creating or processing transfer orders, stock reports, or material documents where the system needs to know which materials or groups to consider.
  When the selection criteria are incomplete or missing mandatory fields.
  
  
  Solution:
  To resolve the WT002 error, you need to:
  
  
  Enter a Material Number  
  
  Provide a specific material number if you want to process or report on a particular material.
  
  
  
  Or Enter a Material Group  
  
  Provide a material group if you want to process or report on a group/category of materials.
  
  
  
  Check the Selection Screen  
  
  Ensure that at least one of these fields is filled before executing the transaction or report.
  
  
  
  Validate Input Fields  
  
  If you are using a custom program or report, check the selection screen logic to ensure it enforces the entry of either material or material group.
  
  
  
  
  Additional Information:
  
  Material Number: A unique identifier for a material in SAP (e.g., raw materials, finished goods).
  Material Group: A classification or grouping of materials that share common characteristics (e.g., all raw materials, all packaging materials).
  This error is a standard validation message to prevent processing without sufficient selection criteria, which could lead to large data processing or irrelevant results.
  If you frequently encounter this error in a custom program, consider enhancing the selection screen with a validation check that forces the user to enter at least one of these fields before proceeding.
  
  
  Example Scenario:
  If you are running a stock overview report (transaction code: MB52) and leave both the Material and Material Group fields empty, the system will prompt with WT002 to ensure you specify at least one to narrow down the report.
  
  If you need further help, please provide the transaction code or context where the error occurs.
