No Records : 2LIS_11_VAHDR, 2LIS_11_VASCL

Hi experts,

Kindly help me with this.

I am trying to get records for 20050301 and 20050719 using Informatica. I cant see any records for this time frame. only 1999 data can be located in RSA3 and RSA7 shows no data for both the data sources ( 2LIS_11_VAHDR, 2LIS_11_VASCL).

Is this a problem with extractor or there is no data coz that will be a big issue then.

How do I know where is the problem and how to solve it.

This is a bit urgent kindly help me.

Thanks
