Hello:
I am new to AL coding. I like to implement OnLookUp within Purchaser Order Extension. This should allow lookUp using Description 2; similar to the default implementation of searching ITEMS by NO. and Description field. This is a learning exercise. I am just wondering whether any references or books are available that I can leverage to start learning this kind of implementation. There is not much within Docs.microsoft.com. DLP has good tutorials but falling short while providing quick references covering most of basic scenarios that I can leverage as reference.
Appreciate any help on this...
