Need to add new line in Service Provider Agreement

Hi All,

In Change Service Provider (T Code- EEDMIDESERVPROV02) screen, I need to add the agreement details for respective Service Provider which I am getting through WebService Call (ABAP Proxy).

Means, new line item for service provider should be created at agreement tab with from date as System date (sy-datum) and To date as 31.12.9999.

Thanks in advance.
