I think I did not communicate properly before. I do not need the split of the transactions on my vendor account. Instead I need the split(view in dimension on my GL).
the invoice I am creating is for my government paying 100$. i.e CPLVEnd-00071(government vendor). The fee i incurred to pay to government would be from different items purchased from different vendors. 100$ would be a mix of 30$ for itemA purchased from vendor1, 35$ for itemB purchased from vendor2 and 35$ for itemC
purchased from VendorC. My offset account would be 23089(government payable G/L account) and i needed my financial dimension to be on this G/L account based on my vendors.
whole of this business case scenario would be with respect to Vendor profit share. every transaction we make on the system would be given a financial dimension and this could be calculated easily without missing(missing any king of expenses incurred on that item) anything.
