Could you please explain a bit for what the data source you used here?
And the field that you would like to work with?
If the Excel table contains all the Addresses and the related ID, then we could take use of Lookup function to find the proper ID with the Address Mapping.
If the Address name is the same as the one you would like to replace with, then please rename the Address field in Excel to Address1 or somthing else,
Then to replace the Address field, the formula should be:
Forall(ExcelTable,
Patch(CDSTable, Lookup(CDSTable, Address=Address1), {Address:ID})
)
Besides, if you are working with Lookup Field in CDS, then the formula might be a little different.
Take a look at the example below:
Patch Lookup field in CDS
