Capturing Webi Report name in BEx Customer Exit variable Code

Hello,

We have a scenario where we have a customer exit variable created on top of a characterstic and that is performing certain function which returns a field from a loop up table and populates it to the variable.

Now, to query that look up table in the ABAP code of the customer exit, we need to set some flag based on the webi report which is triggering the BEx query execution.

So we have SAP BEx query--> Universe --> Webi report

so at customer exit code level, i need to capture the webi report name which has triggered the BEx query execution. Any standard ABAP function which can written me that piece of information or is there any other approach.

regards,

Karthik
