Hi Rajith,
The SID might have move the old transport files into a certain directory. In order to make sure, Logon to system, STMS, Overview, Systems, double click on that SID, click on Transport Tool tab (please see attached).
In the attached image example, we keep the transport in cofiles and data up to 180 days then move into olddate directory. Please check here, if you have anything similar that might be the issue.
Also, the transport files only appear in cofiles/data folder if they are released. Please check in SE01/SE09/SE10, if they are released or modifiable?
If this issue is resolved, please reward me some points.
Thanks.
