Dynamic Sampling In Dax Commands

Hi mahsan_ojaghian ,
To resolve this, use CONTAINS, which can work with a table and column pair. This allows you to compare the current row's RowID with the sampled IDs table.

Try this measure:

IsSelected =
VAR _seed = SELECTEDVALUE('Seed'[Value], 1)
VAR AfterSet =
   CALCULATETABLE(
       'FACT ZWARRBASE_DURABILTY',
       KEEPFILTERS('FACT ZWARRBASE_DURABILTY'[Warr_Period] = 1),
       KEEPFILTERS('FACT ZWARRBASE_DURABILTY'[Warr_Period_status] = "returned after the warranty")
   )
VAR AfterCount = COUNTROWS(AfterSet)
VAR _rateRaw = [RET_RATE_ACT]
VAR _rate = MAX(0, MIN(0.999999, _rateRaw))
VAR SampleN_Base = ROUNDUP(DIVIDE(AfterCount * _rate, 1 - _rate), 0)

VAR InSet =
   CALCULATETABLE(
       'FACT ZWARRBASE_DURABILTY',
       KEEPFILTERS('FACT ZWARRBASE_DURABILTY'[Warr_Period] = 1),
       KEEPFILTERS('FACT ZWARRBASE_DURABILTY'[Warr_Period_status] = "returned in warranty period")
   )
VAR InSetCount = COUNTROWS(InSet)
VAR SampleN = MIN(SampleN_Base, InSetCount)

VAR InSetWithRand =
   ADDCOLUMNS(
       InSet,
       "__Rand",
       VAR rid = 'FACT ZWARRBASE_DURABILTY'[RowID]
       VAR h =
           MOD(
               MOD(VALUE(rid) * 131071, 1000003) +
               MOD(_seed * 524287, 1000003),
               1000003
           )
       RETURN h
   )

VAR SelectedInWarranty =
   TOPN(
       SampleN,
       InSetWithRand,
       [__Rand], ASC,
       'FACT ZWARRBASE_DURABILTY'[RowID], ASC
   )

VAR SelectedIDs =
   SELECTCOLUMNS(SelectedInWarranty, "__RowID", [RowID])

VAR _rowid   = SELECTEDVALUE('FACT ZWARRBASE_DURABILTY'[RowID])
VAR _status  = SELECTEDVALUE('FACT ZWARRBASE_DURABILTY'[Warr_Period_status])

RETURN
SWITCH(
   TRUE(),
   _status = "returned after the warranty", 1,
   _status = "returned in warranty period" &&
       CONTAINS(SelectedIDs, [__RowID], _rowid), 1,
   0
)
Key change: CONTAINS(SelectedIDs, [__RowID], _rowid)
