Requirement date in R3 from APO

Hi Experts,

we are transferring the demand from APO to R3 via transfer profile. Our case is that: we have two product types - and have created two different transfer profiles for each. We have monthly forecast in DP. For one case - the VSF is being reflected as 1st of each month in R3 while for the other case - the VSF is shown as mid of each month (i.e. 15th).

I would like to know if there is any standard way of tweaking the way the VSF gets placed in R3... Looking for some support in this regard.

Thanks.
