How to create SR Category Orders in APO

Hi,

We are using BAPI_PBSRVAPS_GETDETAIL2 to read Planning Book to get parameters (Production, Location, Planning Version,Date/Time Quantity) from Planning Book. Further we want to create SR demand orders in system with below mentioned input:

Product

Location

Planning Version

Date/Time

Quantity

We want to create demand only with ATP category SR for Demand Prioritization in CTM.

Kindly provide options available (i.e. BAPI) to create demand/requirement in APO.

Thanks and regards,

Devang Shah
