[Former Member]

Hell all, Im doing a project where I need to write an upload program to intake a pipe delimited file from the server and then automatically create an invoice in the background for them. so far heres the code for the upload and it works fine. But I am lost when it comes to connecting the two and the bapi aspect. Please help! thanks!
