In MPBM version 2.3.5.0 an import function was added to use the NT submission files to re-import budgets. This can be used in case of data corruption. Note that is should be used with caution as it will overwrite all the existing budget for the accounts and periods it contains.

To use this functionality go to Budgets → Imports → Imports. To import the NT Submission file note that is should of the xlsx format and that it should have a header row (or the first row will not be imported). Click the button "Upload NT submission" to start the import. This will show a SCOA selection popup. This is the SCOA version that will be used during the import. After selecting the SCOA version it will show an upload modal, here you can select the import file.
