If the UI of an SAP
standard transaction needs to be changed profoundly rather than being enhanced,
the re-implementation with SAP Web Dynpro technology can be an alternative to a
GuiXT solution. What has to be considered in this case is the following:
- If the final
transaction is fairly simple, and there are standard SAP interfaces (eg BAPIs)
for reading and updating the data, a Web Dynpro solution can be appropriate,
provided that there is a development team with sufficient Web Dynpro knowledge
- If the SAP
transaction contains complex SAP functions that should be kept (e.g. menu
functions), a GuiXT approach is often better suited.
- With GuiXT it is
possible to start with certain enhancements, e.g. to simplify the screen layout
and the user navigation) and to add further enhancements in a second phase. With
a Web Dynpro implementation, all necessary functions in the SAP transaction have
to be implemented with the first rollout.
- If SAP adds
further fields and functions in a future release, both the GuiXT solution and
the Web Dynpro application may need to be adapted. With GuiXT, it is normally a
question of rearranging a few fields and functions. In your Web Dynpro
application a major implementation effort may be needed in order to add the new
functions.
