如何在 FM EPS2_GET_DIRECTORY_LISTING 中使用 FILE_MASK 参数

Question

I am trying to filter files using FILE_MASK parameter in EPS2_GET_DIRECTORY_LISTING to reduce time searching all files in the folder (has thousands of files).

File mask I tried:

TK5_*20150811*

file name in the folder is;

TK5_Invoic_828243P_ 20150811 111946364.xml.asc

But it exports all files to DIR_LIST table, so nothing filtered.

But when I try with;

TK5_Invoic*20150811*

It works!

What I think is it works if I give first 10 characters as it is. But in my case I do not have first 10 characters always.

Can you give me an advice on using FILE_MASK ?

Haven't tried, but this sounds plausible: https://archive.sap.com/discussions/thread/3470593

The * wildcard may only be used at the end of the search string. It is not specified, what a '*' matches to, when it is not the last non-space character in the FILE parameter value.
