I have implemented a virtual InfoProvider with Services.When I create queries directly on the Virtual Infoprovider the query runs fine and I see the report.
As per my requirement I create an aggregate on the Virtual Infoprovider .Then I define a query on the aggregate .But when I execute this query I get the following errors :
Error reading the data of InfoProvider AG4
An exception with the type CX_SY_REF_IS_INITIAL occurred, but was neither handled locally, nor declared in a RAISING clause
Dereferencing of the NULL reference.
Would appreciate any assistance on this topic.
