Pull from list

Hi,

I want to let the operator move 5 item at a time. And I used pull from list in my model, the request and require number set as 5. Why the operator always transport 1 item at a time?

Hi @J

Since the data type of five pulled items would be in the form of array, you can use run sub flow to achieve this. Refer the model attached below.

Hi @Sri_vikas K ,

I used the sub-flow to achieve it. But I'm wondering why I don't have to use the sub-flow and it can achieve it.

The difference is that by using the Load task you invoke the load time of the task executer for each item.

Your unload technique isn't even invoking that once since you're using MoveObject - and for that you don't even need to pop objects off the array you can just tell it to move the array in one visit to the activity.

You pull from list five items. They are stored in an array. But there doesn’t exists an automatism to create a tasksequence job to transport all items of an array. By default an input from an array returns only the first element of this array. You must build a logical code loop structure to load all items of this array and later to unload all items of this array again.
