If edi document is exported, you must have some records in application and/or exchange repository when you export. If there is nothing, that means no export was done (you can also check edapprx_ref table for batch number). First check trading partner settings. Then check in Trading Partner Parameter Maint (edtppmmt.p) if you have correct parameters (logical and Character...). If is all ok, then set debug level to 9 and check .dbg file. In most cases is something wrong in combination between trading partner, trading partner parameters and transformation definition.

Hi, pls check if you have correct setup into 35.13.10 Trading Partner Parameter Maint and EDI Invoice History as Yes in 7.3.13 Customer Scheduled Order Maint. Then use 126.96.36.199 Invoice Export Audit Report to get session number if earlier document failed.
