It is possible to bulk fulfill multiple sales orders, but not with a single Item Fulfillment.  Have you considered adding a custom field to link each IF together?

For example, create a field called “Shipment Batch” and set this to the same value for each IF.  The NetSuite side is going to have multiple transactions, but you could use this field to group/consolidate your shipping documentation together.

if the Lot Number is “123456” and you decrement from Label XY and increment for Label XYZ, you would still see the “Transaction Serial/Lot Number”  = “123456” in a Transaction saved search for both items so long as you aren’t deleting the original receipt/bill.  This field in a search is a text based lookup, so even though the internal ID if the inventory number record has changed, the Lot Number remains the same.

The label needs to be marked as ‘Preferred’ in order to print the template from the item record or from a transaction.

If you are using Print Checks & Forms > Item Labels, you can select the desired template prior to selecting items and submitting.

Advanced BOM allows you to create BOM and BOM Revisions which can be associated with multiple items and are able to be preferred in a specific location.

Phantom BOM is a configuration which is used to group a configuration of components — and consume inventory from the components directly rather than requiring an assembly be built first.  Typically this is needed for Subassemblies in which a manufacturer does not want to keep stock of the subassembly.

The VRA Packing slip is linked through the VRA custom form.  You will want to make sure there is at least a single template marked as preferred, but the pack slip template can be configured as below.

I don’t believe this is possible without scripting.  With a script though, you can grab the appropriate array of items from the IR sublist and display these in a selectable list as part of a field also generated by the script.  Since this scripted field would only be visible while the record is open, you would want to then store the selected value in the custom field you’re using today.

Are you generating the QR code from NetSuite?  I’m not sure if you are looking to remove all other values stored in the QR code or extract the Serial Number from the string returned by scanning.

Scanning hardware will read the values into a field, so if you want to extract out a specific data element you need to know what the delimiter is and have a script pull the desired value out.

This is not supported for some reason, but user events and workflows are supported on the Department record type.  In theory you could use a workflow to execute a client action.

Do you have any workflows/scripts running on the custom record?  Sometimes this error can be thrown if another record is being generated programmatically, and display it as if you were creating a new custom record entry.
