Is there any one who can help me out .

Give more clue about how to identify the input file from the 4 generated output files.

we have an input folder Src_files the files
like EX:- name_Mail, name_Ril, S924_0049_CN, Name_pp were inserted into the folder at 1 file at a time or 10 to 15 at time .

so first we need to sort the files in the input folder then once the folder get updated we will trigger it in informatica and the output will be
name_Mail we get four outputs. input file name _G , input file_N, input file_N_E, input file_P
name _Ril we get four outputs .input file name _G , inputfile_N, input file_N_E, input file_P

so with the out_file_name we need to check which file has been loaded into the out put folder, then delete the corresponding input file in the input folder.

this process need to continue till the input folder has zero files in the input folder.
