Item queue structure

[MassimilianoBe1]

Hi I have 5 items in code with a particular structure (name, surname).
For business needs a new field (address) must be added in the structure. So I would have items with different structures in queue. When I run the getitem from the queue how can I manage it all?
thanks

Hi Massimiliano - you could use an undefined collection for the output of Get Next Item. An undefined collection is one that has no fields, no structure. The advantage this brings is that it can be used to receive any collection output and it will automatically assume the correct structure. The disadvantage is that because the collection is undefined, there are no column names to drag & drop, you have to type everything manually.

Hmm OK. That sounds like the 'next item' is really an old item and not one with the new structure. How are you introducing the new collection format to the queue? Is it with Add to Queue (ie create a new item) or Set Data (ie change an existing item)?

Hi,
So for that you can check whether the new added column is there in item data or not before setting the data .
if the column is exist then its a collection with new structure if not then its a old collection without the address column.

You can use the BP Utility - Collection Manipulation. The action is called "Collection Contains Field"

Hi Massimiliano.. Is it possible to Mark the old items as Exception yourself, from the Control Room - Queue Management ? That way, the GetNextItem will not pick them, and will pick only the new ones with the updated structure.

You can use BP Utility - Collection Manipulation to check where column is exist or not.
