error key: RFC_ERROR_SYSTEM_FAILURE

Hi all

I have a problem during a RFC.

I call a function with the JCO but, if I fill all the fields that I have to pass to the FM the JVM returns this runtime error:

[code]

Exception in thread "main" com.sap.aii.proxy.framework.core.BaseProxyException:

Data area for accessing table is too small.,

error key: RFC_ERROR_SYSTEM_FAILURE

at com.sap.aii.proxy.framework.core.AbstractProxy.send$(AbstractProxy.java:150)

at bi9032.BI_9032_PortType.zhr_Bi_9032(BI_9032_PortType.java:16)

at bi9032.Startapp.main(Startapp.java:50)

[/code]

In particular the structur in FM has a field 16000 char long.

thanks for your help,

bye
