Sales Volume in Rebate Agreement not updated..!!

Hello Xperts,

I am using standard Rebate Management. When I create invoice, the Rebate Condition is getting updated correctly along with the correct Rebate Agreement but it is not reflecting in the Rebate Agreement. When I check the Rebate Agreement, it shows the Condition Records maintained but it does not show the Sales Volume. Also it gives an error "the sales volume for agreement XXXX is not current". I tried a lot but could not solve the same. I tried to debug also and I found few things and found that it is linked with Information Structure updating. I checked in below menupath

SPRO > IMG > Sales & Distribution > Billing > Renate Processing > Activation Of The New Rebate Procedure From Release 4.6A > Activation of Rebate Procedure

Here, the value for Update for S136 was 1 which means "Synchronous updating (1)". I changed it to "No updating" and now it is working but this is a kind of work around and I cannot deactivate the Info Structure.

Does anybody have idea on this?

Quick reply would be appriciated.

Thanks in advance.

rgrds,
