The Code option takes you to the Implemented Class where you can make any additional ABAP code changes that you may require.
The methods can be redefined by clicking on .

Method Name	Purpose
Set Model Data Each Time Form is loaded	Allows you to programmatically determine and set default values for fields within your data model. Parameter I_FIRST_TIME will be set to X if this is the first time the form is loaded. It will be blank on subsequent loads such as when the form has been submitted and the approver has opened it for review.
Perform Action at any Time	Provides a way to implement logic that can be executed at any time from within the application. These actions can be called from button click events (FabAction) or directly from JavaScript.
Validate Data before Save	Allows for backend validation of data before the data is saved and the next workflow step is executed.
Enhance Data Before Save	Provides a method that can enhance data during the save process. This method can be used to determine and populate calculated fields.
Perform Actions when Status Changes on Save	This method is called after the Validate and Enhance methods and can be used to execute specific functionality when the workflow steps change. Parameters I_CURRENT_STATUS and I_ACTION will be populated with the action that was performed and the new status. Changing the status can be achieved through the C_STATUS_REDETERMINED, C_NEW_STATUS and C_NEW_APPROVAL_LEVEL parameters.
Check and Send Notification	If email or other notification is required when the workflow enters a specific stage (e.g. Approvals), this method can be used to send the email or trigger the notification. For each step in the workflow configuration, there is a Email Required checkbox. This allows for emails to be turned on and off through configuration rather than making code changes. In the method, the base class method should be called (call method super->check_and_send_notification) which will return a boolean parameter e_email_to_be_sent. The value of this parameter is set based on the Email Required checkbox and the code should check whether this is set to true before sending the notifications.
Determine Approvers when Data is Saved	If the approvers are being dynamically determined then this method is called to allow the developer to populate the CT_APPROVERS parameter with the appropriate approvers.
Determine Approvers for Roles	Used to determine which approvers will be associated with each role when using the Enhanced Workflow with custom roles.
Evaluate Task/Outcome Requirements	Allows for the determination of Enhanced Workflow requirements through ABAP code. The method will be passed the requirement ID as configured in the workflow and provides the ability for the developer to evaluate whether that requirement is true or false.
Determine Approvers when SAP Workflow is Used	When using SAP Workflow and the approvers are being dynamically determined, this method is called to allow the developer to populate the CT_APPROVERS parameter with the appropriate approvers.
Handle Escalations	The logic for handling escalation triggers is done by implementing method ESCALATION_PROCESS. New approver(s) can also be determined based on the escalation level reached. Methods DETERMINE_APPROVERS_ON_SAVE or DETERMINE_APPROVERS_WORKFLOW can be used to determine and set these approvers based on the escalation level (import parameter I_ESCALATION_LEVEL). Program /IQX/ESCALATIONS_PROCESS need to be scheduled to run periodically as a background job with a variant that includes the Form Name. It is recommended to schedule the job to run every 15 minutes.
Format Attributes in Worklist	This method allows the developer to select which attributes should be displayed in the MyForms application. This provides a way for users to easily distinguish between different requests in MyForms by using unique values (e.g. Description, Request Type, Cost) from the data model.
Format Icon in Worklist	The icon for the application shown in the MyForms app can be changed through this parameter however it is strongly recommended that the developer select the icon from the Properties dialog to provide the optimal performance.
Set Search Fields in Worklist	The Set Search Fields in Worklist method (FORMAT_MY_FORMS_SEARCH_FIELDS) is used to configure which fields (up to 5) that can be stored at the header level so that searching and filtering can be performed. Currently this stores to the header table for manual retrieval however later versions of My Forms will provide searching and filtering capabilities based on these fields.

Note

Methods redefined by the FAB Workbench tool will have pre-populated set of codes that can be used as a guide. Below is a sample redefinition of the method "Default Fields first time Form is loaded" having initial set of codes.

Note

Methods not available in the Form-Life Cycle dialog can be manually be re-defined from the class.

Step-by-step guide

How tro redefine a method from FAB

Click on to bring up the Form-Life Cycle dialog
Click on beside the method that you would like to get redefined or implemented
Note
Ensure that the class is not opened in change mode otherwise the redefinition of the methods will fail
Provide the transport request number
Click on again to display the redefined method.
