I need some pointers to tell me what went wrong.
1) i created SYS08 SKU Details a column Country made in-----PARENT(Supplied By)
2) In INV02 i used the formula---- 'INV01 Inventory Ordering'.Safety Stock Exception Count[SUM:'SYS08 SKU Details'.Country Made In] but i came out the error below.
I have P3 aggregated to P1 in INV01, INV02 has G2 Country which i used SYS08 SKU Details to get the COUNTRY.

What did i go wrong?
