Group measure into date ranges
I have one table with dates of a part repair and another table with operating times. Is there any way I can create a measure to find the total of operating time between repairs? I'd need a way to create a new column to show what part number we're currently on, so part 1 will be before the first repair, part 2 will be between the first and second repair, and so on and so forth. I could make a giant messy if statement except I need a way to assign it dynamically between any number of rows. Any ideas of where to start with this problem would be greatly appreciated.
EDIT: attached the 2 data sets. The first shows hours of operation, the second has the dates where parts were changed.
Hi BolaSquirrel,
You could try to use M code to see whether it work or not
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("ZY1BDsAgCAT/wtkEAS3pW4z//0YTW6jIdbKzMwY0KMCVbiQkhlkC4ZfwRvoiZISRMtFoOfFnQYoTSTdicZfaJ/mkmyQ/4Ro31ynpmdaUVkvLRgTmfAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [rig = _t, date = _t]), #"Changed Type" = Table.TransformColumnTypes(Source,{{"rig", Int64.Type}, {"date", type date}}), #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 0, 1), #"Grouped Rows" = Table.Group(#"Added Index", {"rig"}, {{"all", each _, type table [rig=number, date=date, Index=number]}}), #"Added Custom" = Table.AddColumn(#"Grouped Rows", "Custom", each Table.AddIndexColumn([all],"newc",1,1)), #"Expanded Custom" = Table.ExpandTableColumn(#"Added Custom", "Custom", {"date", "newc"}, {"date", "newc"}), #"Removed Columns" = Table.RemoveColumns(#"Expanded Custom",{"all"}), #"Replaced Value" = Table.ReplaceValue(#"Removed Columns",each [newc],each if [rig]=1 then [newc] else null,Replacer.ReplaceValue,{"newc"}), #"Sorted Rows" = Table.Sort(#"Replaced Value",{{"date", Order.Ascending},{"rig", Order.Ascending}}), #"Filled Down" = Table.FillDown(#"Sorted Rows",{"newc"}), #"Filled Up" = Table.FillUp(#"Filled Down",{"newc"}) in #"Filled Up"Best Regards,

I've editted my initial post with the data. The first data set is a collection of working times. The second data set is when parts were changed out. So for rig 1 the repair dates were 2/15, 2/17, 3/23, 5/1, 5/4, 5/5, and 6/4. I'd like to add a new column to the first table that lists a part number. For anything before 2/15 it would be part 1, for 2/17-3/23 it would be part 2, for 3/23-5/1 it would be part 3, and so on and so forth. I'm not sure what the best way to tackle this is since there's a variable number of days between new parts. And I don't know how many rows I'll have for any particular rig.
