• What is the cause and solution for SAP error message WSTI_CALC051 - Position the cursor on the desired inventory document item ?

  SAP Error Message:
  
  WSTI_CALC051 – Position the cursor on the desired inventory document item
  
  Cause:
  This error occurs when you try to perform an action (such as posting, changing, or displaying data) on an inventory document in SAP, but the system requires you to explicitly select or position the cursor on a specific line item within the inventory document before proceeding. Essentially, the system cannot determine which inventory document item you want to work with because no item is currently selected.
  
  Explanation:
  In transactions dealing with inventory documents (e.g., MIRO, MIGO, MB1A, MB1B, MB1C, or custom inventory postings), the user interface often displays multiple line items. Certain functions or buttons require the user to select a particular line item by placing the cursor on it. If you try to execute such a function without selecting a line item, SAP throws this message.
  
  Solution:
  
  
  Position the cursor on the desired inventory document item:
  
  Before executing the function (e.g., posting, changing, or displaying details), click on the line item you want to work with so that the cursor is on that line. This tells SAP exactly which item you intend to process.
  
  
  Check the screen layout:
  
  Make sure you are in the correct tab or section where the line items are listed.
  
  
  If using a custom program or enhancement:
  
  Ensure that the code logic requires the user to select a line item before proceeding, or modify the code to handle cases where no line item is selected.
  
  
  
  Related Information:
  
  This message is common in inventory management and warehouse management transactions where multiple line items are displayed.
  The message is a standard SAP message class WSTI_CALC related to inventory document calculations.
  If you encounter this message frequently and it disrupts your workflow, consider training users to always select the line item before performing actions.
  In some cases, this message can be bypassed by customizing the program or screen logic, but this should be done carefully to avoid processing errors.
  
  
  Summary:
  
  Cause: No inventory document line item selected when required.  
  Solution: Click on the desired line item to position the cursor before proceeding.  
  Additional: Ensure proper user training and check custom code if applicable.
