The company has developed a PPS-relevant Purchasing Document application using Unmanaged RAP (RESTful ABAP Programming Model). By taking a copy of the standardized Purchase Order (PO) and Purchase Requisition (PR) applications, the goal is to implement additional functionalities specific to PPS (Production Planning and Scheduling). Additionally, certain GUI functionalities not yet migrated to Fiori, such as the Payment Plan for Purchase Order Items, will be integrated into the new application.
