Not able to enter values in billing plan tab

Hi Friends,

I am using periodic billing and have to create invices thro' contracts. Now I am creating contracts, but I am not able to enter any net value in billing plan tab ,it's coming graded and each line item is blocked with with workflow block.

While creating the contract with periodic billing item category type material, what ever amount we enter in item->condition type( say for example 2000) and in the billing plan tab say 4 line item of dates are planned the at each line item billing value value is 2000 so total comes as 2000x4=8000( net value).

How can I enter the amount at each line item ?

Any pointers.

Regards

Ashutosh
