It seems like you're encountering an issue with the "DATEADD" function in Power BI where some records are resulting in blank values. To troubleshoot this problem, you can follow these steps:

  1. Check your Data: Start by inspecting your data source and the columns involved in the "DATEADD" function. Ensure that the input values in these columns are in the correct date format and do not contain any anomalies or outliers. Make sure there are no null values in the date column that might be causing issues.

  2. Review Your "DATEADD" Function: Double-check the syntax of your "DATEADD" function to ensure it's correctly structured. Verify that you're using the function parameters in the right order. For example, the syntax typically looks like this:

DATEADD(interval, number, start_date)

 

  1. Make sure you're specifying the correct interval and that the interval, number, and start_date parameters are valid.

  2. Handle Errors: If there are any issues with the "DATEADD" function, it might return null or blank values. You can use functions like "IFERROR" or "IF" to handle potential errors and avoid displaying blank values. For example:

IF(ISBLANK(DATEADD(interval, number, start_date)), "Error", DATEADD(interval, number, start_date))

 

  1. This will display "Error" if the "DATEADD" function results in a blank value.

  2. Data Type Compatibility: Ensure that the result of your "DATEADD" function is of a compatible data type with the column where you want to display the result. If there's a data type mismatch, it could lead to blank values.

  3. Check for Filter Context: In Power BI, the results of your measures or calculated columns may be influenced by the filter context. Ensure that there are no filters or slicers applied that might be causing the discrepancy in results.

  4. Data Profiling: Use Power BI's data profiling tools to examine your data and identify any outliers or inconsistencies in the date values that might be causing the issue.

  5. Update Power BI: Ensure that you are using the latest version of Power BI. Sometimes, issues with functions like "DATEADD" are resolved in newer versions. Since you mentioned using version 2.121.903.0, make sure you are running the latest updates available as of your version.

By following these steps, you can hopefully identify and resolve the issue with the "DATEADD" function in Power BI and prevent records from becoming blank when they shouldn't be.
