We are trying to decide between using SAP Portal v. SAP GUI for accessing the core SAP functionality in HCM, FI, SCM, SRM, CRM, PLM etc.
We have chosen a bunch of business packages and we have out-of-box BSP applications, and those functionalities will be available through the portal. In addition, we are evaluating if we should expose the <u>entire SAP GUI</u> through portal using Transaction iViews - SAP GUI for HTML (e.g. all of FI, PLM).
We are not focusing on custom development options using BSP, WDP for ABAP/Java, Visual Composer given the large effort involved. The total user base is ~15,000, and SAP GUI power users are ~5,000 for any given functionality (say HCM).
1. What are the pro/cons of using Transaction iViews versus SAP GUI? Primarily, what are the performance implications of using ITS-based iViews?
2. What would be the non-ITS options that may not involve significant development effort?
