Filename mask in NFS of Linux

Hi Experts,

In an NFS folder say /test/outbound/ which is on Linux server of PI, there are two sets of files like ABC<<timestamp>>.txt and gABC<<timestamp>>.txt & SAP PI should pick up only gABC<<timestamp>>.txt set of files and ignore ABC<<timestamp>>.txt files.

I tried giving gABC*.txt in Filename of sender channel. But the files are not getting picked up even though the files are placed with <sysID>adm user in to that folder. Kindly help.

Rgds,

Naveen.
