Dear Greg
Thank you very much for your help. It looks that what you have described needs
to be done with VB or Java scripts.
Without scripting and even if I filtered the table for a specific row as you
proposed, I will not be able to edit xpath (in rules actions) to reach my
specific field in the specific row.
When I add a rule, add action within the rule, and select "Set a Field Value",
I am only restricted to the selection of a field without editing its xpath.
This would set the value of the field in all rows in the table even after
using a filter for a particular row.
If you agree on what I am saying, then I have to use VB script.
