work days issue in batch job run KO8G

Hi PM Guru,

I am trying to run KO8G in a batch on a monthly basis.

In the workday tab, I am supposed to specify schedule to either beginning or end of month.

I chose END of month and a factory calendar.

However, for workday only 01-19 is enabled which is defined as valid workday.

Please kindly let me know if it is the right way to schedule a periodic run for KO8G and help me with this issue.

Thank you,

Sally
