PA 20 : no data display after selecting the Choose icon

Hi Experts

In Pa20 for a custom infotype (9002),after giving the personal no,when i go with 'overview' option ,many of the records for that pernr are existing.

But,when i select a particular record and go with 'choose' option,(it takes to a different screen)no data is getting displayed for that record.this is happenning with all the records and it is only happenning with this custom infotype(9002).

My requirement is to get the record details when i go with 'Choose ' option.

Any help in this regard wud be appreciated.

Thanks
