# Running Total & Cubes

Hello,

I’m looking to breakdown a customer order into pallets which are under 45 cubic ft. I attempted a two method to get pallets under 45 cubic feet but kept coming up with pallets over 45 cubic feet.

The closest I’ve gotten is with the follow method (Method B in the attached workflow) is

1. Calculate the running total up to 45 cubic feet
2. Assign a Pallet ID
3. Group by Pallet ID to confirm the pallet is under 45 cubic feet

Does anyone know how I can update the workflow to always build a pallet under 45 cubic feet?

Hi @KKF Welcome to KNIME Forum

I created this wf Calculate PLT Cube V2.knwf (102.7 KB).

It consists of 2 parts. First I created a record for item. This gives 230 items to distribute over the different pallets. For the distribution I used a recursive loop. Every loop the (remaining) records are split when the pallet amount of 44.9 cubic ft has been reached.

See if this works for you.

Thank you! This is very helpful! A few question if you don’t mind

For the One Row to Many node, is this node selected to improve performance of workflow’s with larger data? Originally, I didn’t have this node and had to update KNIME.

For the Row Splitter node, is the range checking to provide some kinda of tolerance compared to specifying a constant value of 45?

Hi @KKF

Maybe this solution will create a dataset that is too large to handle? But see for yourself. Alternativly you use a Group Loop to proces every order one by one.

You can configure the Row Splitter with the a constant value 45. That is up to you. I had no special reason for 44.9.

All the best with your project. And if this solution works for you, mark this post (click the 3 … dots) as solved. Happy KNIMEing
