We are developing one tool to update PM task list in mass. program has option to attach multiple files for header, header long text, operation ,operation long text etc. when we are deleting header or operation long text, lines get deleted but checkbox which indicate that long text exist is not getting unchecked. We are using standard FM EAM_TASKLIST_CHANGE. On going through one blog I came to know that this FM doesnot help in unchecking this box.
My question is how can we get that checkbox unchecked.
