Open Period Control not opened all the periods of organization in hierarchy.
PFA the document for more details.
Please Note: This worked fine on 12.1.3 but on our upgrade system R12.2.12 it is not working.
Ran the program with number of periods to open as 0 as the master org ie ABO CIL Indirect Organization already had the Sep period opened.
Expectation was that all the 72 child org Sep inv period will be opened but none opened.
