It is possible to individually change the funding for an invoice, or to assign one funding string to a series of invoices at one time (mass reallocation). If an invoice is individually reallocated and then accidentally reallocated using the mass reallocation feature, the original changes to funding will be lost.
When assigning a funding string to many invoices, it is possible to redistribute an invoice that has already been split to more than one funding string. In this case, the split funding strings are replaced by the single funding string that the user assigned.
Unfortunately, it is only possible to restore an invoice back to its initial funding. If multiple funding changes are made, it is not possible to selectively "undo" those funding changes. The funding must either be reverted all the way back to the initial funding or manually changed.
