DTP is not extracting data from PSA after transport to QA

Hi,

After transport from DEV to QA, all DTPs are not working (all are activated alongwith transformations) and showing request status Yellow. When we mark it green, no data available there. However if we check this request in debugging mode it shows all records.

For DTP monitor, pl. find attached screen shot.

Anyone has any idea on resolution of this issue.
