I am currently working on BW HR reporting and in that context temporal join of hierarchies seems relevant for reporting organizational assignment.
1. I can see that temporal join of hierarchies must be enabled on infoobject level, e.g. on 0ORGUNIT. Will it afterwards be necessary to enable it on hierachy or query level? We do not want to get in a situation where just enabling temporal join of hierarchies on infoobject level affects existing hierarchies or reports based on this infoobject.
2. To what degree will performance be affected?
3. Will temporal join of hierarchies work in both BW 3.5 and BI 7 reporting environments? (We have done a technical upgrade to BI7 but still using BW 3.5 queries / web templates)
Appreciate any input on this!
