Dynamic Labels

The purpose of this page is to help you create dynamic labels in iDempiere. There are times when you need to change a label based on some situation:

You are creating a configuration page and you want the label the user sees to correspond to some setting for a given external source. Example: Shopify URL vs Magento URL
You are asking the user questions (like a form) and you want the prompt to change depending on the question.

Quick description of the solution:

Create two fields where one is a read only Column SQL (this is the label) and the second is where the user types in the actual data to be stored.
Flag both fields as Window, Tab and Field window => Tab subtab => Field subtab => Field Only field = Y. This means that neither field will have a label.
Place the Column SQL read only field on your window in location 1 span 1. NOTE: this is where most labels go.
Place the field that holds the user data (text, number, date, etc...) right next to your Column SQL field at location 1 span 2 (you can span as many columns as you wish). NOTE: this is where most fields go.
When you view the window, you will see the two fields right next to each other. The read only field sort of looks like a label (but uglier).
To make the read only field look much better, update the Window, Tab and Field window => Tab subtab => Field subtab => Field Style field to look something like this: "text-align: right; padding: 0px; border: none; background: inherit;" This will make the read only field look just like a label.

Note that using Column SQL is just one way of updating the label value. You can use any of the programming tools available to you to set a fields value (Column SQL, Callout, Default Value, etc...)
