Workflow Analyzer tool fails when run as Concurrent Program

Hi,

When running the Workflow Analyzer tool as a concurrent program, the program completes in a matter of seconds but the output displays the following error message;

Workflow Analyzer is running... Enter value for 2: EXEC FND_CONC_STAT.COLLECT;

DECLARE * ERROR at line 1: ORA-06502: PL/SQL: numeric or value error: character to number conversion error ORA-06512: at line 3

Alternatively, we have run the workflow_analyzer.sql as APPS with SQLPLUS and do not have the same issue. The issue just appears to be when running as a concurrent program.

This is the version we are running of workflow_analyzer_cp.sql
