How To Fix WSTI_CALC017 - Simulation not possible for completed items

SAP Error Message - Details

• 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.

System Response

Check to make sure your entries are correct.

How to fix this error?

Choose one of following options on the selection screen:
Display completed document items
Simulate calculation of the book inventory at count time

Procedure for System Administrators

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• 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 the order is set to TECO or CLSD status.
  
  
  
  If simulation is necessary:
  
  Reopen the order by resetting the status from TECO/CLSD to REL (Released) or CRTD (Created) depending on your process.
  This can be done via:
  
  CO02 for production orders: Use the "Technically Complete" indicator and remove it.
  IW32 for maintenance orders: Remove the TECO status.
  
  
  After reopening, perform the simulation.
  Once done, you can set the order back to TECO/CLSD if required.
  
  
  
  If reopening is not possible or not recommended:
  
  Create a new order or copy the existing order to simulate the scenario.
  Perform simulation on the new/open order.
  
  
  
  Check authorization:
  
  Ensure you have the necessary authorization to change order statuses.

  Order Statuses:
  
  CRTD - Created
  REL - Released
  PCNF - Partially Confirmed
  CNF - Confirmed
  TECO - Technically Completed
  CLSD - Closed
  
  
  
  Transactions:
  
  CO02 - Change Production Order
  IW32 - Change Maintenance Order
  COHV - Mass processing of orders (can be used to reset TECO status in bulk)
  
  
  
  Notes:
  
  Always check with your business process owner before reopening completed orders, as this might affect reporting, costing, and settlement.
  In some cases, simulation on completed orders is intentionally blocked to maintain data integrity.

  Details
  
  
  
  
  Cause
  Simulation attempted on a technically completed or closed order/item.
  
  
  Solution
  Reopen the order by removing TECO/CLSD status, then simulate. Alternatively, simulate on a new/open order.
