Hi,

I want to change the Approver name from Rob Hunt/IT/AMN to Mike Donal/SAM using Agents formula.
I use syntax below but it's not work :
FIELD Approver := @ReplaceSubstring(Approver;"Rob Hunt/IT/AMN";"Mike Donal/SAM");
SELECT @All

Is there anyone can help me to solve this problem.
Thanks in advanced.

Regards,

Djony Arifin
