Nothing to handle when creating a pick or receipt, Zentriq

Nothing to handle means the function you ran found no line it is allowed to act on, not that the document is empty. In practice the quantity is already handled, the source document is not released, or the quantity sits in a bin or a reservation the function cannot use. Release the source document, then check the outstanding quantity and the bin behind the line before running the function again.

Why Business Central raises this error

Create Pick, Create Inventory Put-away, Create Inventory Pick and Get Source Documents all work from a filtered set of lines rather than from everything on screen. A line only qualifies if the source document is released, if there is still an outstanding quantity to handle, if the quantity is available in a bin the function is allowed to take from, and if a warehouse activity does not already exist for it. When none of the lines pass all of those tests, the function has nothing left to write and stops with this short message. Recent versions append the specific reason, for example that the quantity to be picked is in a bin set up for receiving or shipping, which is worth reading before anything else.

The order or transfer order is still Open. Warehouse functions and Get Source Documents only see released documents.
The quantity is already handled: a pick, put-away, warehouse shipment or warehouse receipt exists for the line, or the line is already fully shipped, received or registered.
The quantity is not usable by the function: it sits in a bin set up for receiving or shipping, in a bin excluded by its bin type or warehouse class, or it is only expected on an unposted supply rather than physically in inventory.

How to fix it

Read the full message. If it names a bin or a reason after the first sentence, that sentence is the actual diagnosis and the steps below can be shortened accordingly.
Open the source document and release it with Release (Ctrl+F9), then run the function again, since unreleased lines are invisible to it.
On the line, compare Quantity with the quantity already shipped or received and with Qty. to Ship or Qty. to Receive: if the outstanding quantity is zero, there is genuinely nothing left to handle.
Check whether a warehouse document already exists for the line by opening the related warehouse shipment, warehouse receipt or warehouse activity from the document, because a quantity can only be handled once.
If the message points at a bin, open the bin contents for that location and see where the quantity sits: a bin whose bin type is set up for receiving or shipping cannot serve as a pick source, so move the quantity to a normal storage bin first with a put-away or a movement.
Confirm that your user is registered as a warehouse employee for that location, otherwise the warehouse functions skip it. Adding a warehouse employee or changing a bin type requires an administrator.

How to avoid it in future

This message is nearly always a symptom of an incomplete flow rather than a defect: a document that was never released, a receipt that was posted into a receiving bin and never put away, or a second attempt at a task somebody already did. Making release part of the standard order routine, and putting away receipts on the same day so stock leaves the receiving bins, removes most occurrences. When several people handle the same warehouse, checking the existing warehouse activities before creating new ones avoids the duplicate attempts that produce this message.

Frequently asked questions

Does Nothing to handle mean the order is empty?

No. The lines are there, but none of them qualify for the function you ran. The usual reasons are that the document is not released, that the quantity has already been handled, or that the quantity is not in a bin the function may take from.

Why does Get Source Documents return nothing on a warehouse shipment or receipt?

It only lists released documents whose location matches the warehouse document and that still have an outstanding quantity with no existing warehouse document. A document already pulled into another warehouse shipment or receipt will not appear a second time.
