Re: UDFx error 42884

You've defined
CREATE OR REPLACE FUNCTION mylib.ZGIACART_Z (
  CODART CHAR(17) ,
  DATARIF decimal(8, 0)
)

But are calling with a VARCHAR
mylib.ZGIACART_Z('020146           '   ,  20261231 ))

And in fact your RPG PI has varchar
pCodArt varchar(17) const;

Lastly, you might need to include the decimal point for Db2 to interpret
20261231 as packed.
20261231.

optionally you can cast the literals to the correct type.
