How to keep using the same pulled resource in a campaign?

Hi,

I would appreciate if you could help me with my request. In my example, I have a list of resources that are pulled based on a certain condition. In a specific situation, the resource can be used multiple times (let’s say 5 times) without being pushed to the list (i.e., campaign) while in another situation, it can be used, pushed, and pulled again.

The problem is when I run the model, each time I need to push the resource to the list to use it again in the campaign, When I do so, the other tokens pull the source and interrupt the campaign.

My question is how to keep using the same pulled resource for 5 times and prevent other token from pulling it until the campaign is completed. The model is large and complex so, I couldn’t share it but any guidance will be highly appreciated.

Thanks in advance,

Mohamed

You say that in order to use the resource again, you first have to push and pull it again? Does this have to be the case? Because the rest of your post sounds like you want the same token to use the resource again, so could it be possible to just skip the release/reacquire?

You could have the other tokens wait in a 'Wait for Event' activity instead of directly in the Pull from List' (max wait timer -> release through connector 2). By placing a delay after it (can be 0s if there is no delay for the other token), the token that pushes the value back gets to pull a value from the list first.

Lastly you could also use some label fields on the list to determine who is allowed to pull a token. For instance both the resource and the tokens could have a label 'Reuse'. Only if that label is equal on both, can the resource be pulled. The default value could be zero and if a token is supposed to reuse a resource it is set to 1 on both.
