I'm trying to make an update of several data from one to another list item.

The destination item has to be an null one (the update variable create a new item).

The most part of the times, the update Action gives an error and don't update or update it but replace an existing item.

Throughout the process, there is also needed to update the item created before with

new information. However, when I have several processes running at the same

time, it only updates some items and the others no. I used the action list

Navigator to find the item(s) I need update, through the identification of a

particular column item (made by workflow ID).

Can anyone explain me why this it's working well sometimes and others no?
