Let's walk through a business scenario step by step to create an APL code implementation.

Business Scenario: When creating an e-signature object, the following business logic should be automatically implemented on the creation page:

• Automatically load the company's contract handler as an internal signer
• Load the e-signature contract's customer contact as an external signer

Steps:

This requirement involves creating a UI event APL function bound to the e-signature object.

1. Navigate to the "Custom APL Code" menu in the admin console and click "New APL Function"

2. Enter the APL function information:

   • For this scenario, select Groovy as the development language
   • Choose "UI Events" as the namespace
   • Select "Data Update Event" as the return type
   • Bind to the "E-Signature" object
   • Use business-meaningful names for both Code Name and API Name

3. Complete function writing in the APL online editor and click Save

4. After writing the function, bind it to the calling business:

   • In the global settings of the e-signature object's create/edit page layout
   • Select UI Events, configure event category and trigger conditions
   • Choose the newly created APL function as the execution action

5. Effect after binding:

   • When creating new e-signature data, the creation page will automatically load both internal and external signers

Through these steps, we've completed a full APL code development cycle.
