When a production order operation has the status 'Dispatched' (DS), it means the operation has been firmly scheduled to a specific capacity at a specific time, typically through capacity leveling. To change this schedule, you must use a tool that can interact with this detailed, capacity-constrained plan.

The classic tool for this is the capacity planning table (e.g., transaction CM25), which allows for graphical rescheduling of dispatched operations based on finite scheduling. In SAP S/4HANA, the modern equivalent is the Fiori app Manage Work Center Capacity, which also provides the functionality to view, de-allocate, and reschedule dispatched operations.

A. You can reschedule the operation using lead time scheduling.

Lead time scheduling (e.g., in transaction CO02) does not overwrite dispatched operations, as they are considered fixed by the detailed capacity plan.

B. You can reschedule the operation using infinite scheduling in a planning table.

Dispatching is an act of finite scheduling (allocating limited capacity). Using an infinite scheduling profile would ignore these capacity constraints, defeating the purpose of dispatching.

Fiori Apps Library

"Manage Work Center Capacity": The documentation for this app explicitly lists its key features

including the ability to "Dispatch or deallocate operations that are scheduled for a specific date" and "Reschedule dispatched operations". This directly supports option D. (Access the Fiori Apps Library for SAP S/4HANA 2023 and search for the app ID F1524).

2. SAP S/4HANA 2023 Help Portal

"Capacity Planning Table (Graphical)": The documentation describes the function of the graphical planning table in capacity leveling. It states

"You can dispatch operations that have been scheduled... You can change the dispatch sequence of operations that have already been dispatched." This process of changing the sequence or time is rescheduling within a finite context

supporting option C. (Navigate to SAP Help Portal -> SAP S/4HANA -> Product Assistance -> Enterprise Business Functions -> Manufacturing -> Production Planning and Control (PP) -> Capacity Planning (PP-CRP) -> Capacity Leveling -> Working with the Capacity Planning Table -> Capacity Planning Table (Graphical)).

3. SAP Course S4520 - Advanced Planning in SAP S/4HANA: Unit 3

"Capacity Evaluation and Leveling

" details the process of dispatching. It clarifies that dispatched operations are fixed for MRP and lead time scheduling. It presents the Capacity Planning Table and Fiori apps like "Manage Work Center Capacity" as the designated tools for manipulating (rescheduling) these dispatched operations using finite scheduling strategies. This supports the correctness of C and D and the incorrectness of A and B. (Refer to official SAP Learning Hub for course S4520
