Solved! Go to Solution.
@SBC
Please refer to attached sample file with the proposed solution
Difference =
VAR CurrentTerm = 'Table'[Term]
VAR CurrentSales = 'Table'[Sales]
VAR CurrentNameTable = CALCULATETABLE ( 'Table', ALLEXCEPT ( 'Table', 'Table'[Name] ) )
VAR TableAfter = FILTER ( CurrentNameTable, 'Table'[Term] > CurrentTerm )
VAR NextRecord = TOPN ( 1, TableAfter, 'Table'[Term], ASC )
VAR NextSales = MAXX ( NextRecord, 'Table'[Sales] )
RETURN
CurrentSales - COALESCE ( NextSales, CurrentSales )
Hi @SBC
please try
Difference =
IF (
HASONEVALUE ( 'Table'[Term] ),
SUMX (
SUMMARIZE ( 'Table', 'Table'[Name], 'Table'[Term] ),
VAR CurrentTerm = 'Table'[Term]
VAR CurrentSales =
CALCULATE ( SUM ( 'Table'[Sales] ) )
VAR T1 =
CALCULATETABLE ( 'Table', ALL ( 'Table'[Term] ) )
VAR T2 =
FILTER ( T1, 'Table'[Term] > CurrentTerm )
VAR T3 =
TOPN ( 1, T2, 'Table'[Term], ASC )
VAR NextSales =
SUMX ( T3, 'Table'[Sales] )
RETURN
CurrentSales - COALESCE ( NextSales, CurrentSales )
)
)
Hi @tamerj1 ,
Thanks for your response, i have applied measure which you have provided but it not working as expected, showing all values as "0"

Name | Term | sales | Difference |
HA | 0 | 2.4137 | 0.0118 |
HA | 1 | 2.4019 | -0.0005 |

@SBC
Sales is a measure or a column in the source table? Accordingly Difference should be a measure or a calculated column? Can you provide a sample of the source data just to see how it looks like and what are the granularity of different columns?
@tamerj1 ,
Sales is a column from the source table.Name,Term,Sales are from source we need to show the difference for each sales of term, last name difference should be zero.
Please check below expected output

Hi @SBC ,
Please try the following measure:
Difference =
CALCULATE(
SUM( 'Table'[sales] )
- CALCULATE(
SUM('Table'[sales]),
OFFSET(
1,
,
ORDERBY( 'Table'[Term], ASC )
)
)
)
Here is the result:
The OFFSET function is relatively new, you may need to update your Power BI Desktop to use it.
If I answered your question, please mark my post as a solution.
Best,
Hi @Alf94 ,
Thanks for your response we need output as 0 for the last Name column of term.iam using latest version of power bi.
