Data
Download the template so columns match the engine. Homemade headers fail.
Where to find it: Left menu → Data Management → Import/Export Templates

Step 1
Left menu → Data Management → Import/Export Templates. If the name is missing, your role does not include it — ask an admin in Users & Roles.
Step 2
Download the template for the entity (partners, items, accounts). Fill rows. Keep column names.
Step 3
Bulk import should accept the file. Renamed columns should fail loudly.
Yes. Import/Export Templates is a signed-in workspace screen. This public page teaches the screen with a picture and a link to the feature video. It never shows another company’s data.
The left menu only shows screens your role may open. Ask a company admin to grant the matching permission, or to show you which role should own this step.
Only if the template allows them. Extra mystery columns are usually ignored or rejected.
