A resource breakdown structure with this name doesn't exist. Enter a valid name.

Dear Exports,

I am attempting to upload a Resource Breakdown Structure (RBS) using the FBDI template; however, I am encountering the following error during the import process:

Error Message:
"A resource breakdown structure with this name doesn't exist. Enter a valid name."

Could you please assist in identifying the cause of this issue and advise on the necessary steps to resolve it?

Thank you for your support.
