Breaking summary value into detail calculated rows

[bhm]

Hi,

I am looking for some solutions to the below problem. There is a list of activities, which has durations in days and value either in $ or in hours (Table 1).

Another table shows working hours per day for each activity ( 8 hours or 10 hours per day) (Table 2)

Now I want to convert the duration into hours based on the 2nd table reference, then expand these activities and values per  8 or 10 hour (based on the 2nd table). Something like below:

Table 1:

Activity	Duration (days)	Value
A	20	2000
B	30	5000
C	50	3000

Table 2:

Activity	Hours per day	Total Duration
A	8	=8x20 = 160 hrs
B	10	=10x30 = 300 hrs
C	12	=50x12 = 600 hrs

Table 1 needs to be converted to:

Activity	Duration (hr	Value
A	8 hr	=(2000/160)*8
A	8 hr	=(2000/160)*8
A	8 hr	=(2000/160)*8
A	8 hr	=(2000/160)*8
A	8 hr	=(2000/160)*8
...up to 20 rows	... up to 20 rows	... up to 20 rows
B	10 hr	=(5000/300)*10
B	10 hr	=(5000/300)*10
B	10 hr	=(5000/300)*10
... up to 30 rows	... up to 30 rows	... up to 30 rows
C	12 hr	=(3000/600)*12
C	12 hr	=(3000/600)*12
C	12 hr	=(3000/600)*12
... up to 50 rows	... up to 50 rows	... up to 50 rows

Any suggestion / help is greatly appreciated.

Thanks

Try this:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WclTSUTIyABMGBkqxOtFKTkCOMUjEFCbiDOaAhUEisQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Activity = _t, #"Duration (days)" = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Activity", type text}, {"Duration (days)", Int64.Type}, {"Value", Int64.Type}}),
    #"Merged Queries" = Table.NestedJoin(#"Changed Type", {"Activity"}, Table2, {"Activity"}, "Table2", JoinKind.LeftOuter),
    #"Expanded Table2" = Table.ExpandTableColumn(#"Merged Queries", "Table2", {"Hours per day"}, {"Hours per day"}),
    #"Added Custom" = Table.AddColumn(#"Expanded Table2", "DayNum", each {1..[#"Duration (days)"]}, type list),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "DailyValue", each [Value] / [#"Duration (days)"], type number),
    #"Expanded DayNum" = Table.ExpandListColumn(#"Added Custom1", "DayNum"),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded DayNum",{"Duration (days)", "Value", "DayNum"}),
    #"Renamed Columns" = Table.RenameColumns(#"Removed Columns",{{"Hours per day", "Duration (hours)"}, {"DailyValue", "Value"}})
in
    #"Renamed Columns"

Thank you so much, it worked perfectly. Thanks a lot.

NewStep=#table({"Activity","Duration","Value"},List.TransformMany(Table.ToRows(Table2),each let a=Table1{[Activity=_{0}]}? in if a=null then {} else List.Repeat({List.FirstN(_,2)&{a[Value]/a[#"Duration(days)"]}},aa[#"Duration(days)"]),(x,y)=>y))
