Increment Value Of Token On Global List

Good Day! I have tried various coding practices and other global table referencing techniques

I wish to increment the value of my tokens (From "Warehouse Trucks") by type (On my "Bunker Bulk Inventory" global table), I have a Global table called "Material Quantity" which has the quantity of increment by type.

What customer code is necessary as seen below to increment it as such, by using the "Material Quantity" global table? It's as if the increment value operation doesn't happen with my incoming tokens and therefore doesn't update on my global table.

testing.fsm

Thank you in advance!

Hi,

The value in your global table wasn't changing because you were accessing it in a way you could only read it, not change it.

To solve that the easiest way, I have used the "Write to GlobalTable" predefined custom code. I also added a label to the tokens called "index" which represents the index of each token created (the first one will have index=1, and the last one index=68), in order to access the correct row in the "MaterialQuantity" table.

I also attach a new version of the model that includes this changes: testing.fsm

Let me know if you have any further questions. I hope it helps!

Thank you very much for clearing up my confusion! Happy modelling :)

It seems to be not updating certain materials in the global table. Is there an explanation for this? For instance, material of type 6 was set to a very high quantity yet it does not increment Material6 in the global table.

It almost seems as if the increment value is capped below 1000. Therefore I cant increase for example Material 6 by a 1000 for a delivery

I didn't connect the new code block, in case you needed to change something else in it to match your model's logic. I don't know if that could be the reason why it isn't working for you.

I attach again your model with both updating codes connected; the one on the left increases the quantity of the material types by 32000, while the right one increases it by 200 (read every time from the "MaterialQuantity" table).

Let me know if you have any further issues or if I'm understanding anything wrong about how you want it to behave.

Hi @Paula LG , I have made the reconnections etc. The problem that I'm facing is when I use values that are not 200 (I had only used 200 as a place holder). As seen below, when such quantities are used, it does not update the inventory for some weird reason... Please find attached the model with such changes :)

Hi,

The problem was the index label was not correct (my bad!) and it always read the first increment quantity (which was 0). I fixed it like this:

I attach the model with the new changes: testing.fsm
