HI,
Thumb rule : You can see only standard datasources in RSA5
All customized and installed datasources will be in RSA6.
I think you need to activate your Infoset again in SQ02. Try to display the data by selecting some fields along with the newly added field. You should be able to see the data correctly here.
After that, come to RSA6, you will find it and activate the DS again here.
Follow this wonderful doc: http://scn.sap.com/docs/DOC-11616
