Dear all,
we are migrating a database from 10.3 to 11.1 but dataflow do not work. We start to check this dataflow
Net Sales (A) + Credit Notes (B) = Sales (C)
A and B has these entities: Day, Document No, Order, Item
C has these entities: Day, Customer, Order, Item
Document No and Customer are into a relationship. All relationship are checked and normalised. Consider that these dataflow "opens" new tuples of data because A has day1,item1,doc1 and B could have day1,item2,doc2.
We tried to perform these procedure:
Case 1 - NOT WORKING
A+B = C changing both calculus dominion and sparsity properties

Case 2 - NOT WORKING
We tried to define temporary cube A' and B' with same entities of C so the procedure became
A' = A
B' = B
C = A' + B'
Case 3 - NOT WORKING
We tried to open sparsity using
C = A
C = B
A + B = C
in these case we also experienced that BOARD performed only C = a, ignoring following steps.
Case 4 - NOT WORKING
We tried to open sparsity using
C = A
C = C + B
In all of the previous cases we tried also to select just a customer in a limited period of time (2 months) but the procedure does not work. We try also to define the dataflow into a dataview and perform a Learning Mode to create version of cube. As not working I mean:
- in some cases we experienced that BoardEngine and BoardWebApiEngine stopped automatically without user did it
- in some cases we had to stop it because BOARD was not responding
- in some cases BOARD performed the dataflow but number were strange
Checking on log I saw that it occurred Tuples.[Intersect]+ that probably is a new algorithm, I was not able to find any references about it.
