Re: How to import multiple header rows into a module?
If this is a module-to-module import and you need to map all the dimensions from Module A to Module B, you can create a saved view in Module A with the dimensions in the page instead of the columns. If you import that saved view, the dimensions will all be on the rows and mappable to the new module.
Importing from saved views is often best for module-to-module imports because they can be optimized with filters, etc. and are less prone to breaking the import if updates are made to the module.
