C             2000

A             1000

D             2500

E             1500

I need solution as in following format

Region    Value      Regionoccurance

A             1000       1

B             500         1

C             2000       1

A             1000       2

You can first add an index column in Power Query or in the source then add the following column to your table in the model:

Column = 
COUNTROWS(
    FILTER( Table4 , Table4[Region] = EARLIER(Table4[Region]) && Table4[Value] = EARLIER(Table4[Value]) && Table4[Index]  <= EARLIER(Table4[Index] ))
)

@Viraj16Agate , refer to this video from Curbal, that can help. But in this you might need an index column first

In dax

countx(filter(Table, [region] = earlier([region]) && [Index] <= earlier([Index]) ), [Index])

You need to create index in power query
