Report for exceptions / errors after Refresh
Hi,
I have created a dashboard by linking 2 tables say Table A (Fact Table / Transaction Table) and Table B (Dimension Table / Master Table). The data in put method for Table A is through folder extraction. Each month I will update the folder with the previous month's file / data. So when I refresh the data, Table A will be updated with latest data.
So my question is if some of the line items in Table A doesn't have any reference in Table B, it would reflect as an error. Is there any way where I can generate an exception report (in the form of a table dashboard in Power BI itself) for the line items which don't have any data links in Table B? So that I can update Table B for the line items I got in the error report / Exception Report.
For ease of understanding, the link between the tables is on Item No (unique / Primary key in Table B).
Hii abhijit_raghava
You can create an exception report in Power BI by identifying records in Table A that don’t have a matching Item No in Table B. Simply create a calculated column using IF(ISBLANK(RELATED(Table B[Item No])), 1, 0) and then filter a table visual where the value is 1. This will display all unmatched records, helping you easily find and update missing entries in the dimension table.
Create a calculated column in Table A:
Exception Flag = IF(ISBLANK(RELATED('Table B'[Item No])), 1, 0)Hi abhijit_raghava,
There are various ways to achieve it
- Recomended (Less efforts)-> Power Query - Anti join exception table -> You can merge table A with table B, create join in Item No. Join type Left anti, this table will only have the rows which are not present in table B
- Calculated table (Using DAX) - Create table using below DAX Exception Items =
EXCEPT(
VALUES(TableA[Item No]),
VALUES(TableB[Item No])
) - Add calculated column in table A, Mapping Status =
IF(
ISBLANK(
RELATED(TableB[Item No])
),
"Missing Mapping",
"Mapped"
)
Out of above recommended is that you create a separate table using Pwoer Query.
