Availability Control not adding up amounts
the all mighty SCN and Google didnt bring me any look on my issue with S_ALR_87013561 - Availability Control.
Im having trouble in finding a solution which will solve the sum up function in a standard transaction.
The case is as follow. The bellow picture shows budget compared to fact, but columns Distributable, Assigned and Available are being totaled up (marked as blue cell)
Any ideas why is this happening?
