Hello,
I am trying to create a DAX calculated column based on a column from a different table that has a relationship with the main table. I am experiencing some errors when trying to merge several tables with a SharePoint table. Is there a way to create a calculated column based on the relationship?
The two tables have relationship on ID and trying to create a calculated column on Table A based on a date column on Table B using IF function.
So is it possible to use IF function to reference a related table?
Left side is table1 and right side is table2.
| ID | Date1 | Calc Col | ID | Date2 | ||
| 1 | 1/1/2022 | IF(Date1==Date2, 1, 0) | 1 | 1/1/2022 | ||
| 2 | 3/1/2022 | IF(Date1==Date2, 1, 0) | 2 | 3/1/2022 | ||
| 3 | 4/2/2022 | IF(Date1==Date2, 1, 0) | 3 | 4/2/2022 |

Hi @cferv_77,
If you're having troubles with the relationships, you can disable it and try to apply manually using USERELATIONSHIP.
And then create a measure like this, you can also apply some conditional like you mentioned.
Measure =
CALCULATE(
SUM(Table1[Value]),
USERELATIONSHIP(Table1[Id],Table2[ID])
)
Hope it was helpful.
Regards,
Douglas.
