Error of Phases cannot be dispatched or deallocated while Dispatch

Dear All,

When I dispatch the Order by using transaction CM25 with

Overall profile SAPCRPG001

System is throwing below error -

Phases cannot be dispatched or deallocated

Message no. CY420


Currently you cannot dispatch phases directly.


If you want to dispatch or deallocate phases, dispatch or deallocate the operation. The phases that belong to it are thereby also dealt with.

Need expert advice....

    The error message CY 420 seems to be correct when you are dispatching or deallocating a


    You should not be dispatching phases from planned order or process orders!!!

    Only operations can be dispatched because the resources are assigned at the operation level (not the phase level) in PP-PI. This is standard functionality.

    The behavior is due to the fact that generally phases of an operation are executed on the same work center of the operation. In fact, the standard profiles used for PP-PI in the planning table

    eliminate should this issue by only displaying the operations. Please review the same data in standard transaction CM29 (or use CM25 with standard profile SAPPI_G001).

    • Hello Rahul

      The entired order is rescheduled, considering the dispatched operation as a constraint.

      It means that another operations will be scheduled, considering the dispatched operation dates and the relationships defined on the master recipe.
