Error in relationship between two models have more keys in asp.net core 2.1

Problem

The relationship from 'SalesFooter.SaleHeaders' to 'SalesHeader.SalesFooters'

with foreign key properties {'SalesOrderNo' : int} cannot target the primary key

{'SalesOrderNo' : int, 'SalesType' : int, 'SalesYear' : int, 'BranchCode' :

int} because it is not compatible. Configure a principal key or a set of

compatible foreign key properties for this relationship.
