    (1) Yes. If you change a standard service it is like changing any other standard SAP core object....there is a chance that SAP will overwrite your changes...say with a service pack or hot fix or similar.

    (2) Yes. Read the documentation on ITS debugging. It is a major pain in the ass so I typically do it the "low brow" place statements in the code to display values, messages, etc. =)

    Have fun with it!

    Adding a screen will entail a good bit of development.

    First, the backend code...

    Starting at the backend, create a custom "Z" version of the program that the transaction code WW20 uses (can be found via t-code SE93).

    Modify transaction/program to add new screen and incorporate it into your flow.

    Follow with typical activation, testing, etc. of regular dynpro developement.

    Create custom t-code, such as ZWW20, to call your custom program.

    Now to ITS changes...

    Create a custom service (copy whatever service called WW20 before) and make sure to set the ~transaction parameter to now call your custom t-code.

    Change existing template names to match the name of your new custom program. For example, if your custom program is SAPMZWW20 and the standard program is SAPMWW20 and you have a template for screen 100, you would rename the template from SAPMWW20_100 to SAPMZWW20_100.

    For your new screen, you will need to generate a template. Create a new template and tell the "wizard" which screen (your new one) to generate it for.

    Follow with typical clean-up, testing, publishing, blah blah blah.

    That should do it. Now you will need to publish out your ITS service and use it instead of the standard one.
