AL Basics – Part 2 [Table]

Today we will discuss about tables.

To Create a Table Create filename.al file, as one shown in example. Folder is not compulsory, I am using to just keep my files in arranged way.

TAB-1

You can choose File -> New File or press 【ctrl】+ N or using tool button on Project folder as shown above. Give meaningful name and .al extension is a must.

Once you get your file in editor, you can start coding from scratch or can take the help of Snippet ttable and continue their after.

Let see what happens if I type ttable in the editor window.

TAB-2

As you start typing the assist window will guide you with available options.

You can press anywhere you will get the list of options available for that section.

We will see this in a while.

First let understand different sections in table object where you will write your codes, or set properties etc.

You can remove your Global Variable and Trigger section if you have nothing to define or not required in your case.

TAB-3

Suppose you are in Table property section and want to know what all properties are available in AL you can place your cursor at desired place and press 【ctrl】+ < Space Bar>. A list of options available will be shown to you, you can select required property and complete your syntax.

TAB-4

Similarly you can do in other sections of table structure also, you will always get the list of things you can do in that section.

Let’s complete our one sample table, with few Table Property, Fields and Fields Property, Keys.

TAB-5

This is a sample Table.

I have commented DrillDownPageID & LookupPageID Table Properties as this page are not available at this stage will add later.

I have defined Caption & TableRelation for my field Depot.

Caption for Field “Slot Duration” also Option String and caption for same.

I have defined Primary Key for the table.

I have defined the fieldgroup for Dropdown.

At this moment I don’t want to define Global Variables and Triggers for this table so removed.

We will get into more details in our next post.
