RE: AL code to auto populate a field from one page to another having same table
Hello,
I have gone through your question and analyze the issue and as per my understanding you need to add your custom field Description into Purchase Order List and this field is available on Purchase Order page right now, for that we need to create one extension and add that field.
below is the code to add this field.
Purchase Order Page in​​​​​​​ Description field is already available:

Purchase Order List Page in Description field is not available:

You can use this code to add description field.
- Before that you must need to add your dependency .app details in your extension after that you can see your custom field as per below example.

Signed, Sealed and Delivered.
