Hi Rajesh,
If data is there in the backend and also you have confirmed that the function is correctly used.
Have the following query:
1. Does the EPMRetrieveData function contains all the dimension? Since any missing dimension value will be taken from active context. So, what I basically wanted to check is if the model has 10 dimension including Measure dimension, then are you referencing all the 10 dimension in you function.
2. Are you specifying the connection in the retrieve or you are taking the default? If answer to point 1 is yes and for point 2 it is "default" please make sure that the report is connected to the right model.
Definte solution would be to include all dimensions of the model in the function and also specify the conncetion name.
Hope this helps.
Regards,
Kalyan.
