The the last date an inventory discrepancy occurred for one material

09 — Wed, 23 Mar 2022 15:56:32 GMT

Hi, I'm having trouble with generating the first date of discrepancy stock between two softwares. That's mean, I want to write a DAX formula that returns the date of which the gap first happens.

The date that i want is 19/03 for this example below taken in account that a gap happened before on 14/02and it was regulated. Thanks for your help.

Date	Material	Gap
11/02/2022	RM	0
14/02/2022	RM	1
15/02/2022	RM	1
16/02/2022	RM	1
17/02/2022	RM	1
18/02/2022	RM	1

You can create a measure like

Discrepancy date = var currentValue = SELECTCOLUMNS( TOPN(1, 'Table', 'Table'[Date], DESC), "@val", 'Table'[Gap]) return IF( currentValue = 1, var lastNonGap = CALCULATE( MAX('Table'[Date]), 'Table'[Gap] = 0) return CALCULATE( MIN('Table'[Date]), 'Table'[Gap] = 1, 'Table'[Date] > lastNonGap ) )

Hi@Johnt75,

Thank you for replying. I have to work with powerpivot in Excel.

The above formula will not work in this tool.

Hi, 09

If you want to add a calculated column in powerpivot, try to change the measure formula as below:

Result= VAR currentValue = CALCULATE ( LASTNONBLANK ( Table1[Gap], 1 ), ALL ( 'Table1' ) ) VAR lastNonGap = CALCULATE ( MAX ( 'Table1'[Date] ), FILTER ( ALL ( 'Table1' ), 'Table1'[Gap] = 0 ) ) RETURN IF ( currentValue = 1, CALCULATE ( MIN ( 'Table1'[Date] ), FILTER ( ALL ( 'Table1' ), 'Table1'[Gap] = 1 && 'Table1'[Date] > lastNonGap ) ) )

Thanks for your help.

I would like to know if it is possible to work with measures because the table in the example is actually a pivot table.

Regards,

Hi, 09

If so, johnt75 's solution should work for you.

I'm not sure what you mean by 'The above formula does not apply to this tool'.

At least, it works fine in my pivot table.

Please check my sample file for more information.

Hello all,

The solution that you gave to me works fine. So grateful for that! but i have a problem with a particular case when i always have a discrepancy of stock (which means the earliest date is actually the first date a discrepancy happen). I'll give you an exemple of this case below. Thanks a lot for any help!

Material	GAP	Date
ABC	1	16/05/2022
ABC	1	15/05/2022
ABC	1	13/05/2022
ABC	1	12/05/2022

The result would be 12/05/2022
