To select all files if * is applied
I have a requirement as below
In selection screen of a program there are fields on selection screen as below
in path the path of file is specified and in file name name of file
my requirement is that uptill now the only one file is being picked up and specified in the selection screen now we want to select all files paterns just like we use in search
for eg ig user give value File_* then all files should be fetched begening with File_ same as it works in search for file names ..
