As requested, I am splitting the Manager Workflow Consistency items into separate topics spaced out over a period of time and in order of urgency.
Sales Invoice appears to be pulling code field from Inventory Items which is correct. However its pulling the Name field from Sales Invoice Items which is wrong. So the information looks different from Quote and Sales Orders which pull everything from Code field.
Purchase Invoices however seem to be pulling nothing in the code field for Purchase Invoice Items. I am not seeing my purchase invoice item codes on the purchase invoice form.
I am not sure why this is happening, because I was under the impression that the second most recent update had changed Manager to make it pull from the code fields for Purchase and Sales Invoice Items.
