Adaptive Insights Import from Spreadsheet still generates unmapped account and level even if NetSuite Import Category Mappings reflects all accounts and levels all mapped

The Import Account Mappings, Import Level Mappings and the Import Dimension Value Mappings are used specifically for imports from spreadsheets. These are separate and not related to the NetSuite Import Category Mappings.

Import Account Mappings, Import Level Mappings and Import Dimension Value Mappings are mapped to unique identifiers in the import file. If the identifiers in the import file are different than the existing Account mappings, Level mappings and dimension mappings in Adaptive, the client will need to add the new Account and Level mappings.
