Latest limits on the number of dimensions and cubes supported in an enterprise planning application (2020)



Knowing enterprise planning application (ePBCS) supports many models including Financials, Workforce, Capex, Project and Strategic planning. Each of them contains some model-specific dimensions and supports 3 custom dimensions. 

This will make you question the old number of dimension limits in a planning application overall, earlier this limit was 20. We put some time in exploring these limits and found that the limit is 32!. Obviously, we are not an advocate of having such a high number of dimensions, however its good to know the supported number of dimensions while designing the overall architecture considering long term strategy for the entire landscape. 


We tried to tick the application by creating 30 odd custom dimensions and then initializing a module, as anticipated we got following error message:

 "Number of Dimensions Cannot be more than 32. Enabling the module will exceed allowed number of dimensions"

 Again note, these limits are at the application level NOT at the cube level!  




We tried to explore the number of custom cubes supported, Create option on top right was disabled after three BSO and 4 ASO cubes.  


Cheers!

Multiple Navigation Flows are Active

Image
We have witnessed an issue where application migration or sometimes service restart in PBCS/EPBCS activates multiple navigation flows.  If multiple navigation flows are active you wont be able make changes in any of them, because in order to make change in navigation flow you have to make it inactive. Typically you may end up in following situation:  Solution is pretty simple: 1. Create a copy of any of the existing navigation flow:  2. Give it any desired name:  3. Now, you will see one additional navigation flow, with inactive status: 4.  Make it active: 5.  At this point of time you will have one active navigation flow and two inactive  6. Select the additional navigation flow you have created and delete it  7. Now you are back in business: Rahul S.

For the default value of a RTP in calc member you have a member which is not valid any more for planning application 3. For the default value of a RTP in calc member you have a member which is not valid any more for a plan type Solution: 1. Refresh cube 2.
