Hi Pv,
At RSA1--> transport connection, while moving info area from middle pane to right pane, select required info area only.
Your info area contains all of the above 5000 objects, after moving info area from middle pane to right pane, expand the info area below you may see all of the above objects selected mark. un selec all and just capture info area only at Transport request.
or
while selecting info area, at grouping --> choose necessary object only and move info area from middle to rigth side pane. unselect all object(below info area if any selected) once you moved from middle pane to right side.
after that change pkg and capture in new TR and try to release at SE10.
Thanks
