Hi
To be honest, was unable to understand the exact issue but surely while you are loading the data into Infocube you can use respective logic into the transformation and manipulate the data accordingly.
In our case, we try to release only delta FCST from DP-->ECC, so we extract back the data loaded into ECC into APO BW cube and then we do the comparison between FCST which has been released and FCST which we suppose to release today and only load the Product/Plant/Version into the cube where we have difference.
So as I said above you can have different logic built in transformation. Please let us know if this information help you. Would be also great if you kindly explain the requirement more in detail.
Thanks
