Hi,

can you provide your document structures (input/output) how they look completely?

Did you try setting the InputArray/OutputArray on the LOOP-Step to the listTypes you are using?

These settings iterate over the list presenting only a document instance instead of a DocumentList.

On these instances you can call your service and maybe drop some intermediate variables before going to the next loop iterations. Maybe you need an additional MAP-step for this.

Deriving from your post your Documents are build like this:

item (list), put this one the InputArray of the LOOP

Hi

Note that when working with Lists, when you map from one to another you’re effectively creating a reference to the List, rather than a copy.

Depending on how you’re doing your mappings, I wonder if this is the problem?

Thanks for your help with this.
