• What is the cause and solution for SAP error message WSTI_CALC001 - Enter either material group or storage location ?

  SAP Error Message:
  
  WSTI_CALC001 Enter either material group or storage location
  
  Cause:
  This error occurs when you are trying to perform a transaction or run a report (often related to inventory, stock, or material valuation) where the system expects you to specify either a Material Group or a Storage Location, but neither has been entered. The system requires at least one of these fields to filter or calculate data correctly.
  
  Explanation:
  
  Material Group: A classification of materials that share similar characteristics.
  Storage Location: A physical or logical subdivision of a plant where materials are stored.
  
  In many SAP transactions (e.g., stock overview, inventory reports, or material valuation), the system needs a scope to work with. Without specifying either a material group or a storage location, the system cannot determine which materials or stocks to process.
  
  Solution:
  
  Enter either a Material Group or a Storage Location in the selection screen or input field where the error occurs.
  If you want to process all materials or all storage locations, check if the transaction allows leaving these fields blank or if there is a special indicator (like a wildcard * or a checkbox) to select all.
  If unsure which to enter, consult your business process or SAP functional consultant to understand which filter is appropriate for your scenario.
  
  
  Related Information:
  
  This message is common in inventory management (MM-IM), warehouse management (WM), or material valuation transactions.
  Check the transaction documentation or SAP help portal for the specific transaction you are using.
  If you are using a custom report or program, the validation logic might be implemented in ABAP code to enforce this input requirement.
  Example transactions where this might appear: MB52 (List Warehouse Stocks on Hand), MB5B (Stocks for Posting Date), or custom Z-reports.
