What is the required info that is not included in the header tab?

The correct choice highlights that the Work Breakdown Structure (WBS) Element is the required information not included in the header tab. In GFEBS, the header tab typically contains essential details that provide an overview of the transaction or document. This generally includes basic information necessary to classify and initiate the order, such as project codes, location descriptions, and necessary approvals like supervisor approval.

The WBS Element, while crucial for detailed project tracking and reporting, is generally specified in the line items or detailed sections of the order rather than in the header. The header is meant to succinctly present fundamental attributes of the order, making it easy to identify the basic parameters at a glance. By separating the WBS Element from the header, GFEBS enhances clarity and allows users to focus on high-level order information without overwhelming them with every detail upfront. This distinction is vital for effective order management and execution within GFEBS.
