Problem with data selection in infopackage

HI,

I am facing issue in the data selection tab of the infopackage. The thing is I want to create pseudo delta in two datasources (0FILA_002, 0FIOTP_001). I made TMSTAMP field enabled in the selection. once the datasource is replicated to BW system I can see the field marked as X in the selection column of the datasource. But I am not able to see this selection in the infopackage. I logged into the system again but the issue is same. Infact I deleted the IP and created the new IP but no use.

Please suggest how I can resolve the issue. how can I make TMSTAMP visible in the IP.

Thanks,

Kumkum
