SD - Incompletion procedure trigger before entering material

[LydiaBoulkroune]

Hello SAPiens ,

Is there any way to trigger SD incompletion procedure in sales document before entering material . 

My scenario is : payment methode (in header accounting tab) needs to be filled before entering material because i have a condition type that depends on the payment methode . I have set incompletion procedure but it only gets triggered after entering material (when i save the document) , so i am obliged to update conditions everytime .

Could you please help me on that . thank you !

Why not to set this as mandatory in customer master ?  It will be a standard functionality rather looking at sale order level where you need to go for customs validation.

I tried that but payment method is not fetched from customer master , is that standard behaviour ?
