There is a one to one relationship between Item Category and the Condition Type that drives what type of reduction it is.
This means that for a given Item category, a value is only valid for one specific condition type, and all other condition types (from this list) should be zero.
for eg : for doc type : ZY99
Item category : ZD21 only condition type ZC12 should be valid and all others should come as zero .
How do i go about doing this?
