SD T code for Mass upload value in Billing Plan

Hi All,

Good Morning

Would you please share your knowledge about Billing Plan Tab. I am working in SD Module, Problem is, I have to update the value 2690 Lines in Billing plan tab. I used T code for updating values in Condition tab, nonetheless need to update each and every value in Billing Plan tab in to contract master.

Since its very urgent and new exposure contract, struggling a lot to complete.

Please help me if you are already using T codes in SD Module.

Thanks in Advance
