customer specific GTIN code (MARA-EAN11)

Hi everybody,

is there a way to maintain a customer specific value for the GTIN-code in SAP?

MARA-EAN11 does not give an option to link to a customer. Customer material info record does not have a seperate technical field for this.

Use case: customers request a customer specific GTIN on the labels. (Internal logistics processes should be kept in mind.) Setting up new materials for each case should be avoided.

I appreciate your thoughts on my question. Thanks in advance!
