DAX-How to get end date in a register when end date is not in the table but the line item is removed

Anonymous — Sun, 01 Jan 2023 19:52:52 GMT

Hi All,

Below is the table which has product with Risk date but it has no End date, the line item will be taken out from Risk Category with Weekly file upload as in column File Number & File Date. The end date should be the File Number Date when it was removed. Product Blue & Diamond are the 2 product with 2 cases scenario for below example. If the Product again come back in rsk category the result table should have a new line item with the new Risk start date & new risk end date in future.

Looks like you only need the File Number Date and the Product from your data table.

Data Table:

let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("ddNNCsIwEIbhu2RdSBMoTrb+4EoEXZYuCqZSqA0U9TyexZO5kLTfJNPtuwgPH5O6VkYbbUuzUYU6T+1496opWL34W5q2w8t/P2l992Hwz7QeD6cshSF7ct+3jzBm+RqGdkrjLnSd/ztJ1FOuJ1FPop5yPQl6kpgkMk2lS3Fm7PPQGHFU7POsLM7DYoUNMQPPWpnHeuSxCDzWI4/HyGN14bGMPLfCcxLPrfCcxHMiz8k8J/MqbQUc1EiDBDcIFbhQIxZTpELDHwR58UOM+uYH", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"File Number Date" = _t, Product = _t]), #"Changed Type with Locale" = Table.TransformColumnTypes(Source, {{"File Number Date", type date}}, "en-GB") in #"Changed Type with Locale"

You don't provide any baseline so the dimension tables for the cross join need to be inferred.

Products:

let Source = Table.Distinct(Table.SelectColumns(#"Data Table",{"Product"})) in Source

Dates:

let Source = Table.Distinct(Table.SelectColumns(#"Data Table",{"File Number Date"})) in Source

Then you can load these three tables into your data model.

Using a matrix visual you can emulate the crossjoin, and you can visualize the gaps for Blue and Diamond.

From here you can decide if you really need the aggregated view or if the graphical representation is enough.

You can also explore GroupType Local in Power Query.
