Triggering Specific Sources

Hi all,


I am trying to make a model in which the quantity of arrival makes specific sources trigger. For example, if the arrival is between 8 and 14 items from the clothing source, then I want EITHER Box Source A or B to send one box to Queue 2. If the arrival is 15 or greater, then I want either Box Source C or D to send a single box to queue 2. I tried pulling from a list using process flow and I feel like I am almost there, but I am not sure how to actually make another source trigger. It seems like there are basically random boxes showing up in the queue which is not what I want.


CreateBoxBasedonLabel.fsm


Thanks,

Amit

Hi @Aaupadhye! I looked at your model (it looks good!) the biggest issue I saw were that you need to add a breathe activity and a decide, then you can use two create objects. I also changed some of your sources into queues. The first thing to change is to change the Clothing Items source to push to list in a trigger instead of in Output, that was causing nothing to show up in Queue1:

Then I changed the sources into queues for the BoxSources:

Those were pretty simple and then my process flow ended up like this:

You need the breathe activity so that it pulls the tokens as a group instead of individually so set the request value high (I did 50 but you can really do anything), that way it grabs all the tokens. Then in the decide I did connector by case with the case as token.pulled.length < 14:

You want your cases to be 1 and 0 (1 if true, 0 if false) then I did two create object activities. Both have a 50/50 chance of creating an object in A or B, or C or D, depending on how many were created in Queue1.

I attached the model! Let me know if you have any other questions!

Hi Julie,


I just read through this and went through the model, everything makes perfect sense. As a follow up question- lets say I wanted to have token.pulled.length between two values. Is it possible to write "token.pulled.length>=14 AND token.pulled.length<=20" for example?

Never mind, I was able to figure it out! I just nested some more 'decide' blocks and used the same method with the && to indicate 'and' and my model works how I want!

Conditional creation of items is more a task of create object activity in Process Flow. Once you can decide which Type of box you want to show up in your model, you can call a sub flow process which creates a box in a queue.

Hi Joerg,


I updated my model to have this, but I am confused on why the clothing items do not show up in queue 1. Also, I am wondering how you can assign a certain label name to the created boxes based on the quantity of arrivals going into queue 1.
