Hello Experts,
We have a requirement of creating a relational universe on top of SAP BW Multiprovider (JCO connector) using information design tool.As you all know, doing this, the entire universe, schema, data foundation automatically creates and the entire business layer automatically creates considering all the fields from the multiprovider in SAP BW.
Now, we have a requirement of creating a cascading LOV between company code and plant. i.e. when Company Code is selected in the 1st prompt, the 2nd prompt for Plant should show the Plant values only corresponding to the company code selected.
I could do this using the parameters and List of values options available in the universe by using the following query for the LOV
1.Create LOV CASCADE:
2. Define the query for the LOV CASCADE.
After creating this LOV, linked it to the Plant dimension in the Business layer and then created a test query to test this functionality.
1. Linked the LOV to the Plant dimension
2. Create a test query to check the cascading fucntionality:
3. The functionality works fine as below:
However the issue that i am facing is this functionality works on top of a relational universe on SAP BW Multiprovider(not a query but the entire multiprovider) only when i set the company code Prompt Option in the primary "CASCADE" LOV (which i created and assigned to the plant dimension )to manual entry and disable "Prompt with list of values" in the query panel of the LOV query.
1. Works when the "prompt with list of values" is disabled in the query for company code:
2. The moment these options are enabled, i get the "Circular referencing error" as below when i run the main test query(no change in LOV, no change in LOV assingment to the plant dimension.)
Found an SAP note on this (0001971073) mentioning this was a bug in BI 4.1,SP3 but the same issue also occurred in BI 4.0, SP5 Patch 6.
Wanted to understand is this is a bug in the product or some limitation for Relation universes using JCO connectors on top of SAP BW multiproviders. I know universe on top of entire multiprovider is not a suggestable approach but that is what our current requirement is inorder to enable self service BI for business.
Thanks and regards,
Abhishek
