Error in creating new inventory item

While creating a new inventory item, the Manager is showing this error - is this a bug? @lubos
I am using cloud 21.9.11

I think this is a bug.

There has been an improvement (Allow Cheque clearing function even after lock date - #3 by lubos) to allow the updating of any transaction as long as the transaction is not materially impacting general or subsidiary ledgers. This has definitely caused that. Accounts with zero starting amounts should be allowed by the lock date.

Remove the lock date and go ahead and create your inventory item. It will be fixed.

This should only happen when you create inventory item with non-zero starting balance while lock date is in place.

Fixed in the latest version (21.9.12)
