CM25 - FM or BAPI to replicate Dispatch, Deallocate and Split/Assign functions in a custom program

Hi gurus,

I need to implement a custom program that allows to manually assign order operations (requirements) to personnel numbers.

I would like to replicate some functionalities of the transasction CM25, in particular:

• Dispatch
• Deallocate
• Split Assignment

Could you kindly indicate any FMs or BAPIs that is possible to use ?

Any suggestions will be appreciated.

Thank you

Best Regards

S.
