Author Bio: Shikha is a Software Engineer Analyst in Accenture Services Private Limited. She has been involved in SAP CRM-ABAP and SAP ABAP Projects.

Business Scenario:
Business Design for comments assignment block using transactions to maintain comments for memberships and members. This enhancement deals with creation and deletion of comments on members. As per the requirement when the comments are created for member through supervisor approval or directly to member, the system should create a Business transaction Z004 – Comment: Member or business activity and it should get updated in the note type.
In a similar way for membership: Transaction type Z001: Comment Membership should be created and the comment should get updated in the note type.
There is also a requirement to implement toggle functionality to “Display Deleted comments” and “Hide deleted Comments”.
Overview:
Create a Z-Component ZCCRMLOY_COMENT for displaying comments in custom assignment block- Comments assignment block

Addition of a new comment
On clicking on “New” below code is done on an event handler EH_ONNEW which opens a pop up to add a new comment.
method EH_ONNEW.

On closing the pop up, “Close” event is triggered which creates a business activity for this transaction and update the standard note type with the relevant text and at the same time also update the change history with the created entry.

Deletion of a comment
The logic for deletion of comments is mentioned below in the event handler ‘EH_ON_ONE_CLICK_ACTION’.  The deletion process works in two ways:
If the logged in user is a warehouse assistant then when comment is deleted on clicking “Trash can button “  it prompts for manager override and a manager override reason is filled in with manager credentials

It prompts for a pop up for manager approval.

If logged in user is other that warehouse assistant then the comment is deleted when the “Trashcan” button is clicked. .
