Adding another column to a data table referencing results from another table? MERGE/LOOKUP??
Hi Anonymous
You may have a try by Merge.
Then we select two tables and Period columns in two tables:
Result:
However, when we use calculated table, we can’t use merge in Power Query Editor, so at this time we have to use Dax to build a calculated column.
Effective Date = LOOKUPVALUE ( 'Table'[Effective Date], 'Table'[Period], Data_Calculated[Period] )Result:

Super UserAnonymous , you want period Table 2 to table 1
If there is 1 to Many join between table 2 and Table
New column in table 1
Period = related(Table2[FY Period])
if they are not related to it, not 1 -M
Period = maxx(FILTER(Table2,Table2[effective Date]=Table1[Transcation Date]),Table2[FY Period])
In case you are looking for a period calculation
The tables currently aren't linked; table 2 is just a reference with the correct values for "effective date" which correspond to Period.
