Pass Dynamic Parameters to BADI

Hi Experts,

I have a logic script with a  SCOPE dimension that has a propery called "HCOMPANY" and the  values  needs to be passed to the BADI to make it dynamic.

Below is the logic script:

//*XDIM_MEMBERSET SCOPE = %SCOPE_SET%
//*SELECT (%HOLDING_COMPANY%,"[HCOMPANY]","SCOPE","[ID]='%SCOPE_SET'")

*START_BADI

QUERY = OFF
WRITE = ON

//HCOMPANY = %HOLDING_COMPANY%
*END_BADI

How could the BADi read the values coming from this dimension.

Could you suggest how this could be achieved....

Thanks for your help in advace.
