    Certainly! Here's a detailed explanation for the SAP error message WT122: "Material &1 in plant &2 is blocked by user &3":


    Error Message

    WT122: Material &1 in plant &2 is blocked by user &3

    • &1 = Material number
    • &2 = Plant
    • &3 = User ID who blocked the material

    Cause

    This error occurs because the material in the specified plant is currently blocked in the Warehouse Management (WM) system by a user. When a material is blocked, certain warehouse processes such as goods movements, putaway, picking, or transfer postings involving this material are restricted or prevented.

    The block is usually set manually by a user to prevent further processing of the material due to quality issues, stock discrepancies, or other operational reasons.


    Explanation

    • The material master or warehouse stock for the material in the plant has been flagged as blocked.
    • The block is active and associated with a specific user who set the block.
    • The system prevents transactions involving this material to avoid errors or inconsistencies.

    Solution

    1. Identify the User:

      • Check who blocked the material (user &3).
      • Contact the user or responsible department to understand why the material was blocked.
    2. Check the Block Status:

      • Use transaction LX02 (Display Warehouse Stocks on Hand) or MM03 (Display Material Master) to check the block status.
      • In WM, check the material status or stock status.
    3. Remove the Block (if appropriate):

      • If the block is no longer required, the responsible user or warehouse manager can remove the block.
      • This can be done via transaction LX02 or LS02 (Change Storage Bin) or through the relevant material master maintenance transactions.
      • Alternatively, use MM02 to change the material status if the block is set at the material master level.
    4. Verify Authorization:

      • Ensure that the user removing the block has the necessary authorizations.
    5. Retry the Transaction:

      • After the block is removed, retry the warehouse or inventory transaction.

      • Material status can be set at different levels (plant, storage location, warehouse) and can restrict procurement, sales, or warehouse movements.
    • User Roles:

      • Typically, warehouse managers or quality management personnel have the authority to block/unblock materials.
