Dear All,

As all of you are well aware about CMP2(Resource planning project view),In which i am looking exactly BAPI or any function module which would be helpful to change resource planning(Assigned person, hours etc.) in one go.

Furthre we were planning to make a Web potal to change already planned resoures against project.

Looking for your valuable input on this matter.

Thanks,
