Hi,

You can use the below mentioned formula.

=IF(ISERROR(VLOOKUP(lookup value,Data Table 1,4,0)),VLOOKUP(lookup
value,Data Table 2,4,0),VLOOKUP(lookup value,Data Table 1,4,0))

Here Lookup Value is the value which you want to search in both the table
array.
Data Table 1 is the reference of your 1st Data Table Array and Data Table 2
is the reference of 2nd Data Table Array.
