Validating Long Material Name

[Former Member]

Greetings,

How can I validate a long material name (char 40) with table MARA for input on sm30(table mainteinance view)? [probably there is some conversion involved].Also, can I make this material a foreign key with mara-matnr, given that they have differnt sizes, or all my validations have to be coded in table manteinance events?

I believe that you can't make any automatic validation or Foreign key with MARA as your domains are different.

Better code in maintenance event and check with relevant MARA existence there.
