Dear Team

While posting the budget transfer, system allows to transfer budget even when sender fund center has no budget.
This means that the system is allowing the negative budget.

Dear customer,

When doing Transfer in FMBB (or FMBBC), if there is not consumption done yet (not posted any PO, IR, payment...), Consumable budget might become negative without error. This is correct based on the system logic.

You could configure the Consistency Check to avoid the transfer without error. This is explained in consulting note 983853 - Missing errors from availability control for negative budget.
