i am not quite deep in IDoc, but i have a request to include some new fields into EDI.
I studied some threads here and I know i need to create a new segement with WE31 and create a new extension based on basic type.
my question is , for example, i would create an outbound Invoice, but adding some information from Matrial master
based on the basic type INVOIC02
1. to which knot i should add my new segement into ? e.g. Ext. Mat. Grp (basic data 1) Mara - EXTWG
2. for a new created segment I can only insert field into it
e.g. Ext. Mat. Grp (basic data 1) Mara - EXTWG
i can only inut EXTWG as field name and type EXTWG as "Data element " , would system be able to find the table Mara-EXTWG automatically. I mean how is the connection between the field defined here and the field in data table, where the Ext.Mat.Grp is stored.
3. If I create like that, then in IDoc i would have for every position in Invoice, there would be a segement for the Ext. Mat Grp. ?
