Enhancement of web services

Question

Hi,
I hope I am at the right place in the forum.
I have to enhance a standard webservice with several customer fields.
The documentation is clear about the point if enhancing one field (p.e.: userfullname) you will choose the right place that means related message data type (in our example same root like   username and changeddate).
In my case I need to enhance with several fields ( 12 or 15 )
did some body allready do that?
What is the best solution ? to search for every fields a nearby information and settle it in the same root, with the problem that the fields are then dispatch in the whole message type
OR
modify or add only one root and add all the customer fields in it ? Avantage : there are all at the same place
Desavantage : you gather pears and apple at the same place
Thank you for any advice
Vincent

When you use the Enhancement Framework, you are changing the development object. Therefore your changes will be active for all times that this development object is called.  There would be no way to filter this by parent component.  Only BADIs would have input filters; but then you would have to pass in the parent component name as the filter value when you call the BADI.
Depending upon what kind of Enhancement you implement - if it is coding you could put an IF check or something around your code to only fire under certain conditions. You could lookup the application name or call some other WD API to try to find what you are running within.  Your enhancement would still always fire, but you would have logic so that it only changes the output under the conidtion of the component you want.
