As per the current design, only one Budget can be created for the Cost Center in a given year. Currently, it doesn’t validate based on the Accounts selected in the Budget.
Can you please create a Github Issue to allow multiple Budgets for a Cost Center, unless Account is not repeating?
Perhaps we could also make Budget a Save only document, and not submittable, so that one could add new Account in the same Budget master.
To allow multiple Budgets for a unique Cost Center + Account + Fiscal Year combination , this will also cover scenario of having different monthly distribution for different account for the same fiscal year.
Thanks. You can also consider sending a pull request for improving validation and take Accounts in the consideration as well. That should be better resolve than making budget save-only doc.
In the Github Issues, please do not make specific mentions as he suggested this etc.
