Exception caught in Executive::processeventinlist()

Hi,

I was able to use process flows to create a pallet and then would create boxes onto those pallets but when running the model I seem to get this error indicating that my pallet token has NULL values.

Exception caught in Executive::processeventinlist()

One of the errors is caused by creating pallets directly in the floor storage. The slots are actually to small for the pallets (1m x 1m vs. 1.25m x 1.25m), so FlexSim throws an error that an item without an assigned slot entered the storage.

Either increase the slot size, decrease the pallet size or forego the space requirement.

Furthermore, when you create boxes in the Process Flow you assign them a "Type" label, but you use "Product" in the Find Slot query.

Hi @Felix Möhlmann,


Thank you for helping me change the dimensions, it really helped a lot.

When changing the visual for the pallets to match the paint slots, I get an error saying the Label does not exist. Even when using the transporter to move the pallets onto the racks I get an error for my SQL Query. I am not to sure why the label does not exist.1679527458734.png

If you've not added the label, it will not exist - where did you think you added it? Note that label name (and almost everything else in FlexSim) are case sensitive so pallet.product is not the same as pallet.Product
