hi @v-piga-msft

 

I have a list of DialCode and it Operator. In Table 2 I have list of Phone numbers.

 

All i need to add a column in Table 2 , which will show me the which Operator they belong to.

 

Table 1 :

 

Resolved NameArea String
Afghanistan93
Afghanistan - Mobile AWCC9370
Afghanistan - Mobile AWCC9371
Afghanistan - Mobile Etisalat9373
Afghanistan - Mobile Etisalat9378
Afghanistan - Mobile MTN9376
Afghanistan - Mobile MTN9377
Afghanistan - Mobile Others9375
Afghanistan - Mobile Roshan9372
Afghanistan - Mobile Roshan9379
Afghanistan - Mobile Salam9358

 

Table 2 :

 

93585844????
937745????
937415????
93794455????
93794415????
93734415????

 

Hope these details is fine.

 

Thanks 

 

Hi @grprem81us,

 

For your scenario, I think Lookup value function could help you.

 

You could Spit columns in Query Editor to get the Area Sting num in Table 2 and Close and Apply.

Then you could use Dax formula like below to get your requirement.

 

Column = 
LOOKUPVALUE(Table1[Resolved Name],'Table1'[Area String],'Table2'[Num])

Hope this can make sense of you.

Hi Cherry,

 

I want a Generic Solution. The dial codes are not 4 digits always. It can range from 1 to 11 Digits.

 

If you see your result below , 9374-15 should have got matched to "93" since 9374 is not there. But it is left Blank which is not expected.

 

Thanks in Advance.

 

Regards,
