Pull from all partitions

Hi,

I have a very simple problem: with the process flow I create a list with two partition and I want to pull a value from all entries in the list without defining the partition.

Is there an option in the activity "Pull from list" to pull a value from all partitions of the list?

I attached an example.pullfromlist.fsm

Software Version:

FlexSim 16.2.1

process flow list partitions

Hi.

I have had the same problem as Alessio, and I never did find a viable solution. I worked around it by creating a number of seperate lists and various blocks that pulled from them.

Any help would be appreciated.

Unfortunately, it is only possible to pull from one partition at a time. You can pull sequentially from all your partitions and get some of the same functionality, but you can't put a backorder on the list that will wait for an entry on any partition.

One way to get around this issue, while still "partitioning" your entries is to use a list with no partitions and use fields to partition the entry. You would then use a WHERE statement in your query when you want to pull from a specific "partition".

For example, in this model I have one list with no partitions, but I have three fields (groupA, groupB, groupC) that act as my "partitions". When I need someone from GroupA I pull with a query that says WHERE groupA >0. When I need someone from either GroupA or GroupB I could just pull without a query or with a query that says WHERE groupC >0.
