Another assumption may cause the problem is
I am using qualifier 03 for EAN code. I have maintained EAN in material master and is putting this EAN code in segment E1EDP19 with qualifier 03. However, system is still saying that material does not exist ( I have checked the material in Sales area and language , it exists).
When I change the segment E1EDP19 to have actual material ( 003), system works fine. Basically, qualifier is not having any effect on sales order creation.
Is there any setting I have to do to make qualifier work. I need to put EAN nr. in it.
