TSQL uupdate using row_number

Hello,
i am trying to update using the query attached.
SoNo is a field in itemSO
i get this error :

Msg 4108, Level 15, State 1, Line 1
Windowed functions can only appear in the SELECT or ORDER BY clauses.

Could someone please explain why this is wrong, and tell me what could be a solution?
thanks
update itemSO
set ficAssmb = SoNo + '-' + ROW_NUMBER() OVER(PARTITION BY SoNo ORDER BY SoNo, itemNo)

what is the primary key of your table, please?
say it is named PK
update t
set ficAssmb = n.ficAssmb 
from itemSO t
join ( select pk, SoNo + '-' + ROW_NUMBER() OVER(PARTITION BY SoNo ORDER BY SoNo, itemNo) ficAssmb from itemSO ) n
 on t.pk = t.pk

to explain what is wrong: read the error message... in short the syntax is wrong, ie not supported.
my suggestion will workaround that.
