I created a Power Platform Model Driven application to manage Business Central Purchase Order Lines.
I set the General Section to 2 columns and moved the Quick View form into that section.
I set the General Tab to be 1 column
I added a new section below the General Section
I added a Purchase Order Lines Subgrid to the New Section (with the Show related records checkbox selected).
I hid the Section and Subgrid labels
A row was added to the Subgrid for every Purchase Order Line.
I navigated into the Business Central solution.
I added the "All Purchase Order Lines" view to the solution
I added the Amount Excluding Tax column to the All Purchase Order Lines view.
I clicked the Save & Publish button
I refreshed the Business Central app.
I added all of the other available columns to the view. I clicked the Save & Publish button
I refreshed the Business Central app.
I clicked the + New Purchase Order Line button
I clicked the Save button and the application generated an error.
I navigated to the Business Central solution
I added the Purchase Order Line Main Information form to the solution
I clicked the Edit button
I added the Line Type and Description fields
I ran the Business Central app. I tried to add a purchase order line.
I selected Line Type "Comment" and provided a Description
The application generated an error.
I added the Document Id to the form
I clicked the + New Purchase Order Line button again
The Document Id was automatically populated
I selected Line Type Comment.
I provided a Description and clicked the Save button. The record was saved and the Line Object No. field was updated (cleared)
The Purchase Order Line was shown in the Subgrid
When I selected the record the menu options changed.
I returned to the Business Central Configuration app and selected the Item table
I updated the Item table to Visible
I added the Item table to the Business Central solution
I clicked the Add button
I noticed that a Many-to-one relationship had been added to the Purchase Order Line table
I reviewed the records in the Business Central Item table
I added the Item Id column to the Purchase Order Line table's Main form
I clicked the Save and publish button
I clicked the + New Purchase Order Line button
I selected an Item
I set the Line Type value to Item
I clicked the Save button (notice that I did not enter a description)
Once the record had been saved a Line Object No. value was generated
I clicked the back button to return to the Purchase Order form
