I am not very understand the difference of "FOREACH" on BI Integration Planning Fox Formula. I know there are 4 types of Foreach:
Foreach xxx in Refdata,
Foreach xxx in Selection,
Foreach xxx in Variable.
I saw there are some explain based on BPS, while in Integration Planning not BPS, what is the difference of each, and what is the relationship with the filter which used in planning sequence?
Thanks very much!
