How do i change the head sheet?

Hello.

How do i change the head sheet so i can change scale,  CHECKED BY, DRWG. No., SHEET, JOB No.?

I change change date, title and DRAWN BY.

depends how the backing sheet was created. If they point to attributes after you change them you will need to do the Graphic Update Annotation (i think that's the one) or ALL to show the changes on the drawing.

It's from AVEVA template sheet.
