PersistentID Mapping in the dataport

[jmestep]

I notice there are two new options in the dataport, but I can't find info on them.
Persist the ID translation between your AC5 and AC7 data for imports handled in multiple stages
Use the existing mapping file for this import.

What are those? Is the mapping file something we need to create?

Thanks

Using this new feature you can now import your AC55 store data in multiple stages and still all your objects may be properly linked. Like you can import users in one go, and the orders data later some time and all the orders will be associated correctly to the previously imported users ( if you have provided the correct Id mapping file).

Is the mapping file something we need to create?

You can save the Id mapping file to your Hard Drive when importing some AC55 data, and this mapping file can be later on used for later subsequent related AC55 imports.

NOTE: For multi stage imports the import order for the objects should be same as shown on DataPort AC55 import screen. It is something like Groups followed by Discounts followed by Categories followed by Emails ..... If you have a single AC55 data file containing all objects then you can simply select (checkbox) the desired object for import and can un-check the others to not be included in import process.
