Power bi results not matching with excel

[Krishna09]

Hello all,

when I use multiplication and Autosum function in excel, it gives me correct value. where as when I implement in POwer query, result doesn't match. Can any one suggest me what might have gone wrong?

after calculating sum of multiples, average is calculated.

below is the formulae I am using in Dax.

wap= divide(

sumx(table, table[days]*table[invoice]),sum(table[invoice]))

I applied Pivot in excel and compared values based on categories, only few categories match. other categories have less value compared to the result of excel.
