How can I retrieve a List of BAPIs with JCO?

[Former Member]

Hello!

I want to retrieve a list of BAPIs in Java. Does anyone have a code sample how to do this with JCO and SWO_QUERY_API_METHODS?

Regards,

Jan

Hallo Jan,

you can use the RFC_FUNCTION_SEARCH FM instead. Use "BAPI_*" to get all the BAPIs available in the System.

Here's a solution. I use some of our own Utility-Methods but it shows the flow of control:

String bapi = "SWOQUERY_API_METHODS";

Object object = browser.createFunction(bapi);

JCO.Function _function = (JCO.Function) _object;

JCO.ParameterList _paramList = _function.getTableParameterList();

if (_paramList != null) {

System.out.println(_paramList.getMetaData("API_METHODS"));

browser.setValue(_function, "WITH_OBJECT_NAMES", "X", String.class, -1);

browser.execute(_function);

int size = browser.processTableSize(function, "API_METHODS", -1);

System.out.println(_size);

for (int i = 0; i < _size; i++) {

System.out.print(browser.getValue(_function, "API_METHODS.FUNCTION", i, String.class));

System.out.print(", ");

System.out.print(browser.getValue(_function, "API_METHODS.METHODNAME", i, String.class));

System.out.print(", ");

System.out.print(browser.getValue(_function, "API_METHODS.DESCRIPT", i, String.class));

System.out.println();

}

}

Hi Jan.

I was searching on internet about this topic and your answer is exactly what I was looking for. But I have a problem with this code, and this is that I don`t know how to declare browser. browser is an Object, a list, an array?, or what?

Can you help me, please?..

Thanks.

Hi Diana,

I've written a small example here (refresh my rusty JCo!) which returns just the function names in a Vector.

Hope this helps,

Gregor
