MAterial no issue in ECC for ROC_out

Hi All

I am facing an issue wherein the Length of MAterial is 18 in ECC and the Length of material coming from SNC is 40.

Is there any note that need to be implemented to resolve this issue

I already have the below setting in SNC and ECC

SPRO >> SCM Basis >> Master Data >> Product >> Specify Output Format of Product Number

Product No.length=18

Which Badi need to be implemented and what is the Note no

Regards
