Hi Folks:
I have a dialog that includes three fields (in two different regions) that a user can update, as well as an interactive grid. I need the save button (approve requisitions buttton shown below) to save any changes in the interactive grid as well as any changes in the other three fields.
I know I can have a separate save button on the IG, but that is not what my boss wants. Here is a pic of the form. The fields circled in blue are the fields I need to save changes too:

These are the three fields NOT in the IG that I need to save.
Additional Info field: :P6_ADDITIONAL_INFO
Building field: :P6_BUILDING
Room: :P6_ROOM
The Interactive Grid is in the Approving Official Region.
On the Approving Official Interactive Grid the approval date is what would be changed
(sql for the IG:
SELECT requisition, fiscal_year, approving_official, approval_date, approval_routing, delegate
FROM requisition_approvals
WHERE REQUISITION = :P6_REQUISITION
AND FISCAL_YEAR = :P6_FISCAL_YEAR)

Regions on Form:

Button Info currently for the "Approve Requisitions" Button:

Thank you so much for any help.....
