Hello @A_Flower, it's great chatting with you again.
The publication was accepted by Ahold and marked as Synchronized. According to our most recent Implementation Guide, we do not have the Distribution Method Code as a mandatory attribute for Ahold. While in general it is recommended to resolve all Warnings and Errors on any items, in this case, you can remove the Ahold playlist after solving everything else to no longer see that Warning as the retailer no longer requires this attribute.
We are here if there is anything else we may assist with, please. Thank you.
