MD133 - Overview

• Message type: E = Error

• Message class: MD - Material Requirements Planning (MRP)

• Message number: 133

• Message text: Simulation planned orders cannot be firmed

What causes this issue?

The planned order that was selected is a simulative planned order from
long-term planning.

System Response

Planned orders that are created in long-term planning cannot be changed
or firmed. They are used to check the effects of the simulative demand
program on production and procurement. Thus, a preview is availble of
the planned demand program.
The planned orders are changed or replanned in the operative planning
run.

How to fix this error?

You can only change the simulative planned orders from the results
screen of the long-term, single-item planning.&CAUSE&

• What is the cause and solution for SAP error message MD133 - Simulation planned orders cannot be firmed ?

  The SAP error message MD133, which states "Simulation planned orders cannot be firmed," typically occurs in the context of the Material Requirements Planning (MRP) process. This error indicates that the system is trying to firm planned orders that are in simulation mode, which is not allowed.
  
  Cause:
  
  Simulation Mode: The planned orders you are trying to firm are created in simulation mode. This means they are not yet finalized and are meant for analysis or planning purposes only.
  Order Status: The planned orders may have a status that does not allow them to be firmed. For example, they might be marked as "in process" or "not released."
  Configuration Settings: There may be configuration settings in the MRP or production planning module that prevent the firming of simulation orders.
  
  
  Solution:
  
  Check Order Type: Ensure that the planned orders you are trying to firm are not in simulation mode. You can do this by checking the order type
