You are trying to transport some changes in Adaptation from one tenant to another, but during assemble you are receiving the error message:
"Codes are not in sync with custom order XYZ; reset custom order" (where XYZ is the name of your custom order).
SAP Cloud for Customer
There were changes (e.g. new values, deletion of values, etc.) in the code list after the custom order was created, hence they are not synced now.
You need to reset the custom order mentioned in the message and optionally you can create a new order that contemplates the changes done to the code list.
