WSTI_CALC017 - Overview

• Message type: E = Error

• Message class: WSTI_CALC - Physical Inventory Messages: Book Inv. Calc. at Count Time

• Message number: 017

• Message text: Simulation not possible for completed items

What causes this issue?

You want to simulate the calculation of the book inventory at count time
and take completed physical inventory document items into account at the
same time. However, you can only perform the simulation for active
physical inventory document items.

• What is the cause and solution for SAP error message WSTI_CALC017 - Simulation not possible for completed items ?

  SAP Error Message:
  WSTI_CALC017 - Simulation not possible for completed items
  
  
  Cause:
  This error occurs when you attempt to perform a simulation (e.g., cost estimate, settlement simulation, or any planning/simulation activity) on an object (such as a production order, process order, or maintenance order) that is already technically completed or closed in the system.
  In SAP, once an order or item is marked as completed, it is considered finalized, and no further changes or simulations are allowed because the system treats the data as settled and closed.
  
  Explanation:
  
  Completed items mean the order status is set to TECO (Technically Completed) or CLSD (Closed).
  Simulation functions are designed to work on open or released orders where changes and recalculations are possible.
  Trying to simulate on a completed order violates this logic, hence the system throws this error.
  
  
  
  Solution:
  
  
  Check the status of the order/item:
  
  Use transaction codes like CO02 (Change Production Order), IW32 (Change Maintenance Order), or relevant order display transactions.
  Verify if
