Filter only latest 3-month data

[firdaus62]

In power query, I want to limit the amount of data loaded into the model by only including new data within the last 3 months from the excel.  So far found this forums, however it doesnt work with my case.  Solved: Include only Latest 3 months of data - Microsoft Power BI Community

Example:

• I want only the latest rolling 3 month:                                  1st April 2022 to 31st Jun 2022
• But I get this when I follow the forums:                                Blank result.

I use this filter to filter the Production Month column to only load the latest 3 months data.
= Table.SelectRows(#"Renamed Columns", each Date.IsInPreviousNMonths([Production Month], 3))

For addition info,
- I have production data from Jan 2019 to Jun 2022

- my initial data was in excel format

- my final option is to just filter the excel by only put in the latest 3 month data, however in future when there is new month for new data, I need to replace the source of the excel with updated one manually.

Try this dax

SalesLast3Months = CALCULATE(SUM(Sales[Amount]), DATESINPERIOD('Calendar'[Date], LASTDATE('Calendar'[Date]), -3, MONTH))

Hi & thanks for replying,

 Below is the table that I have, my intention is to filter the data just to show latest 3 months of data so that all my report will reflect to show the latest 3 months data.

Hi @firdaus62 ,

Please try this.

= Table.SelectRows(#"Changed Type", each [Date] > Date.AddMonths(Date.EndOfMonth(List.Max(#"Changed Type"[Date])),-3) and [Date] <= Date.EndOfMonth(List.Max(#"Changed Type"[Date])))

All steps.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("XdhBDt1WDEPRvWRcwCKfZdlrCbr/bRRB2pRXQ458vog/ePz584cuXS7rx99//QrOcDLcGTrDk2EyvBm+DCokGASEoBAYgkOACBKBIlgMi3kPWAyLYTEshsWwGBbDcmA5YfGF4Awnw52hMzwZJsOb4cNHC4kgIASFwBAcAkSQCBTBYljMe8BiWAyLYTEshiWLOnn+k+c/ef6T5z95/pPnP3n+c+E7Hz5aSDAICEEhMASHABEk4k+GxbCY94DFsBgWw2JYDAvPb1gOLPk/uS8EZzgZ7gyd4ckwGd4MHz5aSAQBISgEhuAQIIJEoAgWw2LeAxbDYlgMi2ExLIbFsGRRndV0VtNZTWc1ndV0VtNZTWc1ndU0qmlU06imUU2jmkY1jWoa1TSqaVTTqKZRTaOaRjWNahrVNKppVNOoplFNr2ryP/RcCM5wMtwZOsOTYTK8GT58tJAIAkJQCAzBIUAEiUARLIbFvAcshsWwGBbDYlgMi2HJoiarmaxmsprJaiarmaxmsprJaiarGVQzqGZQzaCaQTWDagbVDKoZVDOoZlDNoJpBNYNqBtUMqhlUM6hmUM2gmlnV5H/ovRCc4WS4M3SGJ8NkeDN8+GghEQSEoBAYgkOACBKBIlgMi3kPWAyLYTEshsWwGBbDcmDJor4LwRlOhjtDZ3gyTIY3w4ePFhJBQAgKgSE4BIggESiCxbCY94DFsBgWw2JYDIthMSx4ARVep4XnaeF9WnigFl6ohSdq4Y1aeKQWXqnFZ2rxnVp8qBZfqsWnavGtWnysFl+rxedq8b1aqOtXXDeiylSZKlNlqkyVqTJVq7j8i4krA2cG7gwcGrg0cGrg1sCxgWvDmhvW3rAGh7U4rMlhbQ5rdFirw5od1u6whoe1PKzpYW0Pa3xY68OaH9b+sAaItUCsCQKrgzA7CLuDMDwIy4MwPQjbgzA+COuDOD+I+4M4QIgLhDhBiBuEOEKIK4Q4Q4g7hDhEiEuEOEWIW4Q4RohrhDhHiHuEOEj8ilSt4vAH/F2j/w3OcDLcGTrDk2EyvBm+DL/b+5NgEBCCQmAIDgEiSASKYDEs5j1gMSyGxbAYFsNiWAzLgeWExReCM5wMd4bO8GSYDG+GDx8tJIKAEBQCQ3AIEEEiUASLYTHvAYthMSyGxbAYlizq5PlPnv/k+U+e/+T5T57/5PnPhe98+GghwSAgBIXAEBwCRJCIPxkWw2LeAxbDYlgMi2ExLDy/YTmw5P/kvhCc4WS4M3SGJ8NkeDN8+GghEQSEoBAYgkOACBKBIlgMi3kPWAyLYTEshsWwGBbDkkV1VtNZTWc1ndV0VtNZTWc1ndV0VtOoplFNo5pGNY1qGtU0qmlU06imUU2jmkY1jWoa1TSqaVTTqKZRTaOaRjW9qsn/0HMhOMPJcGfoDE+GyfBm+PDRQiIICEEhMASHABEkAkWwGBbzHrAYFsNiWAyLYTEshiWLmqxmsprJaiarmaxmsprJaiarmaxmUM2gmkE1g2oG1QyqGVQzqGZQzaCaQTWDagbVDKoZVDOoZlDNoJpBNYNqZlWT/6H3QnCGk+HO0BmeDJPhzfDho4VEEBCCQmAIDgEiSASKYDEs5j1gMSyGxbAYFsNiWAzLgSWL+i4EZzgZ7gyd4ckwGd4MHz5aSAQBISgEhuAQIIJEoAgWw2LeAxbDYlgMi2ExLIbFsOAFVHidFp6nhfdp4YFaeKEWnqiFN2rhkVp4pRafqcV3avGhWnypFp+qxbdq8bFafK0Wn6vF92qhrj8r3/+RKlNlqkyVqTJVpspUreLyLyauDJwZuDNwaODSwKmBWwPHBq4Na25Ye8MaHNbisCaHtTms0WGtDmt2WLvDGh7W8rCmh7U9rPFhrQ9rflj7wxog1gKxJgisDv+tfH/SQbqRGulBGqQX6ePXF4YakSN6RJAoEkmiSUSJKlPldSOqTJWpMlWmylSZKlO1isMf8HeN59/gDCfDnaEzPBkmw5vhy/C7vT8JBgEhKASG4BAggkSgCBbDYt4DFsNiWAyLYTEshsWwHFhOWHwhOMPJcGfoDE+GyfBm+PDRQiIICEEhMASHABEkAkWwGBbzHrAYFsNiWAyLYcmiTp7/5PlPnv/k+U+e/+T5T57/XPjOh48WEgwCQlAIDMEhQASJ+JNhMSzmPWAxLIbFsBgWw8LzG5YDS/5P7gvBGU6GO0NneDJMhjfDh48WEkFACAqBITgEiCARKILFsJj3gMWwGBbDYlgMi2ExLFlUZzWd1XRW01lNZzWd1XRW01lNZzWNahrVNKppVNOoplFNo5pGNY1qGtU0qmlU06imUU2jmkY1jWoa1TSqaVTT/1fz9z8=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t]),
