BAPI_CPROJECTS_COMMIT_WORK Performance Issue

Hi all,

I have created a custom  Program to Upload Roles and Staffing to the Same Roles for CProjects.

We are using the Following BAPIs

BAPI_BUS2177_CREATE

BAPI_BUS2177_ROLE_DIST_SET

BAPI_BUS2177_SKILL_PROFILE_SET

BAPI_BUS2177_STAFFING_ADD

BAPI_BUS2177_STAFF_DIST_SET

After Creating Multiple Roles and Staffing for a Single Project I use FM 'BAPI_CPROJECTS_COMMIT_WORK to Commit the changes.

Then Use  BAPI_CPROJECTS_REMOVE_OBJECTS to Unlock all Objects.

However BAPI_CPROJECTS_COMMIT_WORK  takes long time to commit the changes 15-30 Seconds per Project with average roles and staffing is 3 or 4.

I have already looked for SAP notes around around these BAPIs but do not seem to get and help.

Could you please suggest some help for optimizing these BAPI's

Thanks,

Shashank
