I've a question regarding the assignment GTIN to GTIN type.
If I enter a GTIN in trx. MM42 the system finds automatically a GTIN type. It seems,
that the assignment is related to the lenght of the GTIN.
If I enter a GTIN with 13 digits the system assigned GTIN type HE,
if I enter a GTIN with 11 or 12 digits the system assigned a GTIN type UC.
Where can I find the rules for these assignments?
Thanks in advance for your information.
