Problem while Loading excel files into MSSQL DB using BODS

I have tried to run a BODS job with 76 input files but the job took only  60 files for processing and the remaining 16 files are exist in the input directory.

Is there any setup like how many files to processed for while running job??? Plz help me to fix this issue.

I used scripts for reading files and used function wait_for_file()

$G_DIR_ACT_FILE_PATH=replace_substr('[$G_DIR_ACT_FILE_PATH]' , '\\', '/');

wait_for_file('[$G_DIR_ACT_FILE_PATH]*' , 1, 0, -1, $L_FILENAMELIST , $L_FILECOUNT);
