How do I see how much of a given thing, I pulled from a list?

Hi all.

I have a list where tokens are pushed onto, each with a QTY label between 1 and 20.

I wish to pull between at least 1 and up to preferably 15 units of QTY from this list and add the given quantity to a label on the pulling token to keep track of this.

Pulling from the list works as intended, but I can't seem to find a reference to how much QTY I managed to pull. I looked rather thoroughly through the 'assign to'-functionality, but I found nothing to indicate if I pulled the required 1 QTY or more.

Did I somehow overlook a way to reference the QTY that the puller pulled? (Flexsim 16.2.2)

Best regards. Christian

Edit: I have read through the This Thread (24220), bit it deals with references to the token that are pulled themselves, not a value pulled from the tokens.

Unfortunately, to do this you have to manually figure it out yourself. There isn't currently anything implemented with the List that allows you to get the quantity pulled when using the SELECT statement. It is on our to do list to add this feature.

For now, the work around is to manually sum up the label values before you do your SELECT query and then sum them up again after. This also means you have to ensure that a token is not waiting on the Pull from List if the require number is not met. In this event, send the token to a Wait for Event activity that waits until another token is pushed to the list, then recalculate the total QTY.

It's not pretty, but it does work.

Bump! Is this issue still present in FS2017? I seem to be having the same problem. @Matt Long
