automatically dynamic loading flat files in BW

Hi experts,

In BW we need to load the files dynamically from al11 path automatically with date and timestamp.

we already got a way to load date dynamically with below example but need add time stamp as well along with date.

Let us know any wild card search in BW abap routine will help.

Also let me know if EPS_GET_DIRECTORY_LISTING or EPS2_GET_DIRECTORY_LISTING will work for SAP BW.

Regards,

Venkatesh
