Replace N.a with non null Value corresponding to the same supplier-DAX

[Anonymous1993]

Hi,

I am having a Dax requirement as shown below.

Supplier	Date	Region
Amul	02-08-2022	BE
Amul	02-08-2022	N.A
LGL	02-08-2022	DE
LGL	02-08-2022	DE
Air	02-08-2022	AN
Amul	02-08-2022	N.A
Hitachi	02-08-2022	MN
Amul	02-08-2022	BE
Telecom	02-08-2022	N.A
Intel	02-08-2022	LK
Amul	02-08-2022	N.A
Intel	02-08-2022	N.A
Intel	02-08-2022	N.A
Air	02-08-2022	AN
Amul	02-08-2022	N.A
LGL	02-08-2022	N.A
Air	02-08-2022	N.A

I have few N.A values in Region Columns.i Want to replace these Na with the value in supplier column which has aregion value

Example, if Supplier 'Amul' is Shown as BE region, all amul with N.a should be replaced with BE.

Each supplier will either have only one region or N.a and some regions will have N.a alone which can be left as such.

Hope this is clear.

Thanks in advancefor your help.

Hi @Anonymous1993 
Please use

Region 1 = 
IF ( 
    Suppliers[Region] = "N.A",
    MAXX (
        FILTER ( 
            CALCULATETABLE ( 
                Suppliers, 
                ALLEXCEPT ( Suppliers, Suppliers[Supplier] )
            ),
            Suppliers[Region] <> "N.A"
        ),
        Suppliers[Region]
    ),
    Suppliers[Region]
)
