Function module extractor is not retrieving data

hello,

I have developed a function module extractor but getting Zero records.

I have tried to debug the code and found out that there is record in E_T_DATA but not L_T_DATA.

what could be the reason.

E_T_DATA has 12 records and L_T_DATA has zero records. I guess the number of records should be equal based on the logic.

Thanks,

Bhat
