Date value to string and substring in dd/mm/yy value

Hello Experts

I have a date field which is in dd/mm/yy hh:mm:ss format. In SM Processdesigner RuleSet, I want to set a character field to a value using the date field in the format of dd/mm/yy.

Have been trying some options but not getting the expected result.

Please if anyone can suggest and advise.

Regards

WA
