The FM EPS2_GET_DIRECTORY_LISTING has a parameter file_mask which I guess that it should act as a pattern. I need to read from the AS the files containing a word but the file_mask is working faultly. For example if I pass "*ZIP" it returns a file named '.TXT'. Is there a proper way to use that parameter?
The parameters are described in SAP note 1860206 which I will not quote here because I'm not sure about the copyright status. However, wildcards generally do not work as expected in this case - your best bet is to read without the parameter and filter the table afterwards.
