RMS - I cannot post a delivery because it is on the incorrect business day

This happens when someone has started the End of Day process, not completed it fully and locked their inventory. 

A ServiceDesk ticket is not required.

To action this, open the delivery draft - you will receive an error about the "incorrect business day/inventory locked", but after selecting OK, the draft will open.

Select Delete, which does not delete the order, but will turn the draft into a scheduled order.

Now, run the End of Day process for one cycle to unlock the inventory, and then you will be able to post your delivery.

Continue to follow the Receiving a Delivery process steps.

Once complete, continue to run the End of Day process to catch up to the current business day.
