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.
If it completes successfully it will show the number of imported lines and asks you to view the batch (these batches can also be found under Budget → Import → Import batches).
The import batch shows which lines are valid and which lines are invalid. A line can be invalid since the NT submission files don't contain MSC segments. This means the file only contains the combined budget. After importing this budget must be split over the accounts with different MSC segments. For the accounts that only exist with one MSC account, all budget is automatically put on that account. The invalid lines must be updated before the batch can be pushed. To update these invalid accounts the button behind the invalid tag can be clicked a popup is shown in which the budget can be split over the different accounts.
When all accounts are valid the push button can be used to push the budget imports to the app (NOTE: this will push to the app, not to evolution!).
