BPC 10 - BADI - Get Parameters passed in IT_PARAM

Hi All,

I have to write few BADIs for BPC 10 .

There is a selection screen where user selects the Dimension values for restricting entries ( eg. Time , Category ) when the BADI is run (Run Package ) via EPM Excel. But I am unable to get the values passed here, in the BADI under IT_PARAM. I am able to get QUERY and  WRITE values in IT_PARAM . Can anyone please shed some light on this. I am new to BPC programming, hence would appreciate all help.

Interestingly, when we add a new screen for passing values, I am able to get it in it_param. But I am unable to get the values from the standard selection screen.

Regards,

Suzie
