[ FlexSim 23.1.2 ]

Hello guys, I would like to ask you for help. I need to do quite simple thing in Flexsim, but even I tried everything, I can´t find the answer.

I need to pull from list the closest tote to Operator to load item from it. I don´t know what is wrong. It doesn´t work, token always gets stuck in the "pull from list" block.

Thanks in advance, all the best.

Hello @Milan U3,

This is because you define the puller as the operator but the operator does not have the label mat_index. I changed your assign labels activity to assign the label to the operator and then the query works. You will want to review if the mat_index label can be written to just the operator of if it also needs to be written to the token.

Hello Jeanette, thanks a lot. Unfortunately, there are not any changes in the file You attached- please, could You send me it once more? I would like to try it. Thanks

Just duplicate the assign labels and and set to to token.op to add the the mat_index to the operator.

You're model is going to crash soon afterwards in the delete_rows activity - you should add this clause or actually populate the label with table structured data.

if (virtualtable.numRows)
    virtualtable.deleteRow(rowsqty);

Your model will appear to stop/lock 424.16 as the token in PartsCollecting loops continually in zero time.

Thanks @Jason Lightfoot . I did It like in the picture, but there is still "puller required". Operator does work, but ORDER BY query doesn´t work. What is the reason? Thanks

I´ve just realized, why it doesn´t work like I want. Operator is working according to the "virtual table" schedule and this schedule is fixed (table below)- there is not possible to use ORDER BY, because there is only 1 option in real time (specific row in the table). I am gonna try to fix this, maybe with extra List, pushing selected items from "virtual table" into it.
