Description: The DAX function ‘LASTNONBLANK’ is a powerful tool in the field of data analysis, especially in the context of data modeling and reporting applications that use the DAX (Data Analysis Expressions) language. Its main function is to return the last non-null value from a specific column, filtered by a given expression. This is particularly useful in situations where the most recent relevant data from a time series or a dataset containing blank values is required. The function allows analysts and developers to work more effectively with incomplete data, ensuring that visualizations and reports reflect the most recent and meaningful information. ‘LASTNONBLANK’ thus becomes an essential resource for data-driven decision-making, as it facilitates access to the most up-to-date information without the interference of null values that could distort the analysis. Its implementation is straightforward and integrates smoothly into more complex formulas, making it a versatile option for those looking to optimize their data models and improve the quality of their reports.
