Is there a way of working with changing parameters with JCO?

[Former Member]

Hi,

I'm developing a component that works with the JCO library to connect to a SAP system.

I'm reading the whole documentation and they set ways of working with: Import parameters, Export Parameters and Table parameters. I see no mention of 'changing' parameters. Is this possible with JCO or they only support those 3 I mentioned earlier.

Thanks guys.

Hi Fernando,

of course JCo also supports CHANGING parameters.

At least in my JCo JavaDoc documentation I can find the method com.sap.conn.jco.JCoFunction.getChangingParameterList() for example.

But please note that especially for transferring table objects via RFC, using TABLES parameters is much more performant than using IMPORT, EXPORT or CHANGING parameters,

Just in case you are also in control of the ABAP remote function modules and you can influence their interface definitions.

Best regards,

Stefan
