Parallel for each in document understanding

I am using a Parallel for each and Im trying to have the present validation station open for 3 documents concurrently. it was works for classifications but not for validation. this is error that I have.

Present Validation Station: The automatically determined extracted results references do not match the Document Object Model. They may have been created using a different Document Object Model.

First of all validation is a ui activity so running concurrently is jot recommended

As per error looks like the dom is being currupted or overlapped between instances

Cheers

Is there any to process this concurrently? Batch processing in UiPath Studio for document understanding

@Aki1111

Batch processing can be done …but in batches you cannot use present validation

Present validation needs to be separate or if you want concurrent then use create form task and create a form in orchestrator actions page so that it can be concurrent

cheers
