Adaptive RFC question

[Former Member]

I have a general question: could you tell me the reason why the RFCs to be called in JAVA Web Dynpro should be designed transferring the table values in the "Tables" parameter tab and not the "Import" and "Export" parameter tabs?

Hi Tania,

You need to know first what is import parameter, export parameter and table parameter.

Import enables you to pass single set of values. Export enables you export single set of values. When you have data that is collection of n number of sets of data, use Table (Stucture) for import or export.

E.G.

Suppose, you are trying to see result of a student by Importing roll number of the student. You can use Export parameter to display result (a single set).

But if you want to see reuslts for n number of students by inputing n number of roll numbers, you need to use table structure for inputing the roll numbers and outputing the results.

An ABAP developer needs to document these parameters so that the WebDynpro developer can understand what are input tables and what are output tables.

Need to know more ? let me know.

hi Ashutosh,

Something is not so clear for me: when using tables as parameters, what is the best (in terms of performance) for JAVA Web Dynpro?

1) That the RCF includes the tables parameters in the "Export/Import" tabs. Meaning that we will have

PLANTS TYPE (a TABLE type element)

Or,

2) That the RFC includes the tables parameters in the "Tables" tab. Meaning that we will have

PLANTS LIKE (a STRUCTURE name)

Thank you.

Hi

The second option is what you need to do. Well there is a document on Effective Do's and donts. That is a nice document that will make you understand on how to design a RFC to interact with WebDynpro.

Hope that was helpful.

Hi,

Does it affect performance?

I don't think there is much difference from WebDynpro point of view.

Though, I guess an ABAPer should be a better person to answer your question :).
