It sounds a bit like you are looking for a "Batch" Activity instead of a List. But maybe you can explain more exactly what you are trying to do (e.g. with a small example model)? So we can figure out how to help you!?

@sebastian.hemmann, I am using list as my inventory/storage, I want to check how much I have in my inventory for each SKU before giving production request, so that I can prioritize the one with low inventory and ignore/delay the one with high inventory. I would just like to check the value and not release anything.

In fact it is a Table.query you are looking for.

double sumlabel = Table.query("SELECT SUM(label2) FROM List1.2")[1][1];
print(sumlabel);

List1 looks like this picture:

The value of variable sumlabel is 40.

Please look into the manual howto get a reference of a partition of a list :

Thank you, worked like a charm. I deleted the partition Id and did "group by" in the query statement and it made it even more easy to use.

You could try using the information found in this part of the FlexSim User Manual:

This could be applied to a dashboard or other function so you can read the value.

Here's a specific example where I'm finding the number of items in Partition ID: 3 of "ItemList1" that can be applied with code:

int partID3 = List("ItemList1").entries(3).length;
return partID3;
