SQL & PL/SQL

CREATE OR REPLACE PACKAGE pa_terpaper_usa_ccaps_export AS
PROCEDURE pr_usa_ccaps_export(
i_num_prg_key IN NUMBER,
i_num_process_key IN NUMBER,
o_num_status OUT NUMBER);
END pa_terpaper_usa_ccaps_export;
/

I have defined the procedure in the package.

declare
o_num_stat number;
BEGIN
BUSEXP_OBJ.pa_terpaper_usa_ccaps_export.pr_usa_ccaps_export(15079,15746,o_num_stat);
END;
/



The procedure is compiling . But when I execute the above plsql procedure pr_usa_ccaps_export , I am getting error like

BUSEXP_OBJ.pa_terpaper_usa_ccaps_export.pr_usa_ccaps_export(15079,15746,o_num_st
at);

PLS-00201: identifier 'BUSEXP_OBJ.PA_TERPAPER_USA_CCAPS_EXPORT' must be
