User exit for Source determination LMEQR001 : EXIT_SAPLMEQR_001

Hi Pals,

As any one used this user exit for source determination?

If yes can any one please pass the sample source code because

i tried with all the available Table and export parameters of FM: EXIT_SAPLMEQR_001,

nothing is working.

and as well SAP has not given any sample code for this enhancement in 4.6c system

Thanks,

Veeru.
