web service problem

Hi,

I have a problem with invoking operation after connecting to the web service (OE10.b).

After analyzing the wsdl file with bprowsdldoc, the procedure prototype is:

PROCEDURE operationName:

DEFINE OUTPUT PARAMETER return1 AS LONGCHAR EXTENT NO-UNDO.

END PROCEDURE.

example:

DEFINE VARIABLE return1 AS LONGCHAR EXTENT NO-UNDO.

RUN operationName IN hWebService(OUTPUT return1).

This example code in some cases (if the output parameter array have more than approximately 3500 extents) gives me an error:

Attempt to expand record beyond the maximum allowed size. (444).

Is there a way to invoke that kind of operation?
