EPM cloud - YTD functionality in BSO & ASO both

EPM cloud - YTD functionality in BSO & ASO both

Content

In Oracle EPM cloud, We are trying to set up Year to date functionality(in both ASO and BSO cubes)... How to set up the same in both ASO and BSO together in Planning App?

because in ASO - DTS is not allowed. and then creating alternate hierarchy (with shared members) also gives an error as soon enabled for ASO cube. (because when we create the hierarchy for March , it says Feb can't come in twice in ASO alternate hierarchy)

The other option to explore to create another hierarchy which has MDX formulas in ASO and probably Dynamic Calc Members in BSO cube.
