Rebate condition base value is automatically doubling

Hi,

We created a Rebate agreement and it created the Rebate accruals.

For Rebate, the accruals are maintained at 3% (no scales). When we made an invoice for Rs. 100,000, in the F2 invoice, the Rebate basis is showing up as 100,000 but on the Rebate agreement it is showing as Condition Base Value - Rs. 200,000 and thus calculating Rs. 6000 as Condition value.

We checked whether it is updating the SIS twice and to our knowledge it was not.

Can somebody help me in finding out the possible solution to fix this problem.
