Data is not available in RSA3

Hi Experts,

Data is not available in RSA3 but available in PSA and datasource type is Generic data source with function Module. We cheked in development system it shows fine(in both RSA3 and PSA) but when we cheked in Pre-production system it shows only in PSA but not in RSA3. Please let me know what could be reason behind that one ASAP.

Regards
