I presume you are trying to import the historical sales volume data from Data hub to Supply chain model and 'DAT03 Historic Volumes module' is already created in Supply chain model.
This is an error associated with your import process. Please go to ACTIONS-> EDIT and check if there is any error, if there is an error then I suggest you create the import process once again and run it.
Note: Make sure you cross-check your mapping in 'source model'. If there is a mismatch then direct it to correct source.
Yes, I clicked on 'Edit Mapping', followed by selecting my Data Hub model. This however did not fix the issue. I read a bit more on the community and found an user with the same error message. As per her instructions, I went to Actions - Imports tab - 9.1 Import Historic Volumes - i had to redo the link to the view - Hub_DAT03 Historic Volumes.Export. However, it was originally the right link but for some reason re-linking it fixed the issue.
Is there an explanation as to why or when we would have to re-link a given view?
Usually this happens when a model is moved to another workspace. The links are not broken that easily. Another reason could be that the initial module to which it was linked it was removed so it had to be re-linked to the new one.
You did the relink by doing going to Import Data Sources or Imports?
I went to Actions - Imports tab - 9.1 Import Historic Volumes - i had to redo the link to the view - Hub_DAT03 Historic Volumes.Export - i literately just did cut and paste the link. Dont forget to click Refresh too.
