I am trying to implement BW PS with the new cubes (for example 0PS_C041). In help.sap.com, we can see that the documentation says that with this cubes you only need to insert in the cubes:
0PSGUID, GUID of a PS Object
0PS_OBJ, PS Object Type
and right now is not neccesary to insert infoobjects as 0PROJECT, 0NETWORK, 0ACTIVITY, as they are navigational attributes of 0PSGUID.
My problem is that I need other attributes of 0PROJECT as navigational in my PS new cubes (for example 0PROJECT__0CO_AREA in my 0PS_C041 cube). But how can i insert navigational attributes of 0PROJECT if this field is not in the cube?
As fas as I see, the solution can not be to insert 0PROJECT in my cube, because in this case I can have duplications if someone changes the PSPID in R3. That is the reason why SAP has decided to change old cubes by new ones.
