Split Rows based on Condition

[tejapowerbi123]

Happy Monday Community Members,

I have a below scenarios for your suggestions. I have used list.dates functions but it does not generate correct result because my Contract Months keep changing.

My requirements is that if contract months is >=12 Months then I want to crate  2 Rows with 12 Months Block and if contract is <12 then create one row.let me know if you need more information.Thanks

Start Date	End Date	Contract Length
1/1/2015	31/12/2015	12 Months
1/1/2015	31/07/2015	7 Months
1/1/2015	31/07/2016	19 Months
1/1/2015	31/12/2016	24 Months
1/1/2015	31/07/2018	43 Months
Start Date	End Date	Contract Length	Row Split Comments
1/1/2015	31/12/2015	12 Months	for 12 Months 2 row split
1/1/2015	31/12/2015	12 Months	for 12 Months 2 row split
1/1/2015	31/07/2015	7 Months	for 7 Months 1 Row Split
1/1/2015	31/12/2015	19 Months	for 19 Months 1 Row with 12 Months and 2 Row with 7 Months Split
1/1/2016	31/07/2016	19 Months	for 19 Months 1 Row with 12 Months and 2 Row with 7 Months Split
1/1/2015	31/12/2015	24 Months	for 24 Months 2 row split of 12 Months
1/1/2016	31/12/2016	24 Months	for 24 Months 2 row split of 12 Months
1/1/2015	31/12/2015	43 Months	for 43 Months 3 row split of 12 Months and 1 Row with 7 Months
1/1/2016	31/12/2016	43 Months	for 43 Months 3 row split of 12 Months and 1 Row with 7 Months
1/1/2017	31/12/2017	43 Months	for 43 Months 3 row split of 12 Months and 1 Row with 7 Months
1/1/2018	31/07/2018	43 Months	for 43 Months 3 row split of 12 Months and 1 Row with 7 Months

Hi,

This M code works

let
    Source = Excel.CurrentWorkbook(){[Name="Data"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Start Date", type datetime}, {"End Date", type datetime}, {"Contract Length", type text}}),
    #"Duplicated Column" = Table.DuplicateColumn(#"Changed Type", "Contract Length", "Contract Length - Copy"),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Duplicated Column", "Contract Length - Copy", Splitter.SplitTextByDelimiter(" ", QuoteStyle.Csv), {"Contract Length - Copy.1", "Contract Length - Copy.2"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Contract Length - Copy.1", Int64.Type}, {"Contract Length - Copy.2", type text}}),
    #"Removed Columns" = Table.RemoveColumns(#"Changed Type1",{"Contract Length - Copy.2"}),
    #"Added Custom" = Table.AddColumn(#"Removed Columns", "Custom", each if Number.Mod([#"Contract Length - Copy.1"],12) <> 0 then Number.IntegerDivide([#"Contract Length - Copy.1"], 12)+1 else Number.IntegerDivide([#"Contract Length - Copy.1"], 12)),
    #"Added Custom1" = Table.AddColumn(#"Added Custom", "Custom.1", each {Number.From(1)..Number.From([Custom])}),
    #"Expanded Custom.1" = Table.ExpandListColumn(#"Added Custom1", "Custom.1"),
    #"Removed Columns1" = Table.RemoveColumns(#"Expanded Custom.1",{"Contract Length - Copy.1", "Custom", "Custom.1"})
in
    #"Removed Columns1"

Hi Ashish,

Than you so much for your replay.

Still the result is not showing correct,start data and end date is not showing right

For 12 Months ,

Source without Transformation

Start Date	End Date	Contract Length
1/1/2015	31/12/2015	12 Months

Final Result

Start Date	End Date	Contract Length	Row Split Comments
1/1/2015	31/12/2015	12 Months	for 12 Months 2 row split
1/1/2015	31/12/2015	12 Months	for 12 Months 2 row split

For 19 Months,

Source without Transformation

Start Date	End Date	Contract Length
1/1/2015	31/07/2016	19 Months

Final Result

1/1/2015	31/12/2015	19 Months	for 19 Months 1 Row with 12 Months and 2 Row with 7 Months Split
1/1/2016	31/07/2016	19 Months	for 19 Months 1 Row with 12 Months and 2 Row with 7 Months Split

Let me know if you need more information.

Thanks

Hope this helps.

Hi Ashish,

Thank you so much it is working fine for all the months,Only last confusion for 12 Months 2 Rows start date is showing 1/1/2016.

How to change it to 1/1/2015.

Hi Ashish,

I am working on getting the similar concept but not getting around anywhere.

In my Room booking scenario I have to split my rows hourly .

RoomID	Start Date	End Date	Duration
1	09:00	11:00	120
2	09:00	10:00	60
3	11:00	12:30	90

RoomID 1: should repeat 2 times (09:00-10:00 ,10:00-11:00)

Room ID 2: no repeat

Roomid 3: repeat 2 times 

How can I achieve this in power bi?

[Ashish_Mathur]

Hi,

I only know how to make it work for Dates (not for time stamps).  Sorry, i cannot help.

[tejapowerbi123]

Hi Ashish,

thank you so much for your suggestion.still end date is not shwoing right in 2 rows.It works for me.

[tejapowerbi123]

Hi Ashish,

Thanks

Hello,

i have tried below code  but it did not generate correct result for 12 Months.Does anyone has any suggestions?

let
Source = Excel.CurrentWorkbook(){[Name="TableDates"]}[Content],
#"Changed Type" = Table.TransformColumnTypes(Source,{{"start", type date}, {"end", type date}, {"months", Int64.Type}}),


AddedYearDates = 
Table.AddColumn(
Source, 
"Year Start", 
(fnAddYear) => List.Generate(
() => [YearDate = fnAddYear[start], Counter = 1],
each [YearDate] < fnAddYear[end],
each [YearDate = Date.AddYears(fnAddYear[start],[Counter]),
Counter = [Counter] + 1],
each [YearDate]), 
type {date} ),

ExpandedYearDates = Table.ExpandListColumn(AddedYearDates , "Year Start" ),
#"Changed Type1" = Table.TransformColumnTypes(ExpandedYearDates,{{"start", type date}, {"end", type date}, {"Year Start", type date}}),
#"Reordered Columns" = Table.ReorderColumns(#"Changed Type1",{"start", "Year Start", "end", "months"}),
#"Removed Columns" = Table.RemoveColumns(#"Reordered Columns",{"start"}),
#"Added Custom" = Table.AddColumn(#"Removed Columns", "Custom", each Date.AddYears([Year Start],1)),
#"Changed Type2" = Table.TransformColumnTypes(#"Added Custom",{{"Custom", type date}}),
#"Added Custom1" = Table.AddColumn(#"Changed Type2", "Custom.1", each Date.AddDays([Custom],-1)),
#"Added Conditional Column" = Table.AddColumn(#"Added Custom1", "Custom.2", each if [Custom.1] <= [end] then [Custom.1] else [end]),
#"Removed Columns1" = Table.RemoveColumns(#"Added Conditional Column",{"Custom", "Custom.1"}),
#"Changed Type3" = Table.TransformColumnTypes(#"Removed Columns1",{{"months", Int64.Type}}),
#"Renamed Columns" = Table.RenameColumns(#"Changed Type3",{{"Custom.2", "End"}}),
#"Changed Type4" = Table.TransformColumnTypes(#"Renamed Columns",{{"End", type date}}),
#"Reordered Columns1" = Table.ReorderColumns(#"Changed Type4",{"Year Start", "end", "End", "months"}),
Result = Table.RemoveColumns(#"Reordered Columns1",{"end"})

Hi @tejapowerbi123

I advise you to follow these steps:

• open your query editor
• duplicate your table (so we got table1 and table2)
• in the table2, duplicate the column Contract Length (Contract Length - Copy)
• in this new column Contract Length - Copy, you replace the value  Months by nothing (to keep only the numbers)
• change the format of your column (Text to Whole Number)
• select only the number granter than or equal to 12

• Remove the column Contract Length - Copy because you don't need it anymore
• Use the function Append Queries as New to create a new table made of the table1 and table2

This new table entitled Append1 is what you need if I'm not wrong.

Regards,

CR

Hi CR,

Thank you so much for your suggestion.

Questions 1:What is the do with contract length has <12 ?

Question 2: How is it going to split the column by contract lengths?

Can you please explain me in details?

Thanks

[CR]

Regarding the ones <12, I just kept the original line because, in the table2, I kept only the line >= 12.

Table1: data <12 + data >=12

Table2: date >=12

Append1 = merge of Table1 + Table2 = data <12 + data >=12 + Data < 12 = 2(Data >=12) + Data <12

It refers to your requirement if contract months is >=12 Months then I want to create  2 Rows with 12 Months Block and if contract is <12 then create one row

Concerning the split you are talking about, I'mreally sorry, I just understood what you need ! Well, I'll try to reply tomorrow because you need few steps to get that (not so simple in my opinion) but probably somebody will complete.

Regards,

CR

Hi CR,

thank you so much for your advice. I will wait for your response.
