Manual Pricing for Subscription Order

Hi Experts,

I want to maintain manual pricing for subscription orders.

I did Condition type - 'Rate' as manual entry is priority but its not working.

Whole Condition tab display in Grey Colour(Non input screen).

I also want to create subscription order with function module - ISM_SALES_ORDER_CREATE.

Can we pass condition values through this function module.

Please guide me .

Thanks in advance.
