Dear,

Is it possible to make the system not to generate the SD Invoice Document if an error occurs during the creation of the FI Accounting Document?

What do you mean by above sentence ?

First is creation of SD invoice then only we can create / release that Invoice document accounting to FI point of view .Without generation of Invoice how can we get Accounting part in SAP ?

Due to gaps in the official document numbers, every SD Invoice document must have it's corresponding Accounting Document.

When you come to Proforma Invoice ,it doesnt have accounting part so,there is some inconsistency will be happen if use any user exit or enhancement on your requirement .

How system knows ,there is error ( what type errors ) occurs during FI accounting ? If there is no Error during FI accounting creation then what what will be happen ?

If you have any doubts please let me know .

Note : If any thing is mistake in my post please explain little bit more your requirement .

Thanks,

Naren
