BAPI to Create Maintenance plan

Hi Guys,

1) I want to send data of maintenance plan from third party software to SAP. My requirement is to create/Change Functional location maintenance plan and create /change Equipment maintenance plan.

Can anyone please suggest me bapi to do so.. do i need to use different BAPI"s to do this or this can be handled using 1 BAPI only.

2) What all tables and fields do we need to update while sending a maintenance plan data to SAP.

3) is there any document which i can refer while mapping my fields with SAP fields?

4) Any specific validations i need to apply while sending data.?

Thanks in Advance..

Regards,

Ashish
