if you are using list page for EP,
at your list page interaction class on AX.

do override method initializeQuery and add sortbyfield like example below 

public void initializeQuery(Query _query)
{

_query.dataSourceTable(tableNum(HRSBenefitEntitlement)).addOrderByField(fieldNum(HRSBenefitEntitlement,Employment));
    super(_query);

}

do Incremental CIL after you modify the code.
