use of statefull RFCs in WebDynpro

[Former Member]

Hello,

i want to create a WebDynpro application which uses RFCs. Every RFC call will relay on the fact, that ABAP-Memory updated in previous call can be accessed. What do you think, will it work? is it a correct strategie?

Will it work if i use web service created from RFC and if not-sap application use our rfcs/web services?

thanks

Hi Paul.

My totally personal opinion is that this wouldn't be my prefered design. But I am

not aware of what you wanna do in the backend via the RFCs. What data do you

want to be kept in memory and why?

Hello Sascha,

Our existing application uses ABAP-Memory. Now we want to use this existing modules in WebDynpro. Application will consist on many screens and it does not make sense for us to send to RFC always complete entered data. For every step RFC will called and ABAP-Memory will be updated, so following RFCs-calls must rely on it.

Database will not be updated in every step.

Hi again.

I've never used RFC this way and I am not aware of how the context for the

connection is kept in backend after the call returns, especially when thinking about many

different user of you WD4A application which all use the same RFC Connection.

But as I said I do not know it.

Anyway it seems to be strange for me to handle the R/3 backend like a statefull

application server.

Maybe someone else can help you here.

Cheers,

hi,

you say different user use the same RFC Connection.

I thought that by every start of WD Applicatuion new connection is taken?

For example LORD_MAINTAIN_COMP from SAP uses backend as statefull server

Hi ,

I have used RFC's couple of time in WebDynpro ABAP .As I am doing WD Application for SRM where I require to fetch data from other R/3 servers .

Now do you want something like this . You will pass some parameters to RFC and based on that will updates data in that Remote R/3 and Also send results that you want show over WebDynpro Application .

Please see thread below .See that help you or not.

Cheers
