Read Multiple Line Items

I am creating a bot which has to read multiple line items for the same invoice number. I am not sure what activity to use for making that sequence. Does that has to be part of the Queue Load Process or should be included in the Happy path. Please respond!!

We do not know what your Invoice looks like so none of us here can give you any real answers.

Is it a PDF document? Word? Notepad? SAP? Something else?

Attaching a example invoice would be a good first start.

@fali1 adding to above if it is a pdf it contains images/text etc depending sample we help
