with(
local!employees:rule!MS_IAL_GetAllEmployeeDetails(),
local!skills:rule!MS_IAL_GetAllEmployeesSkills_CDTManipulation(),
joincdts(
joinType:"INNER",
leftCdt:local!employees,
selectFromLeft :{"firstName"},
rightCdt:local!skills,
selectFromRight:{"skillName"},
onLeft:"employee_Organization_ID",
equalsRight:"employee_Organization_ID",
leftAlias:{"employees"},
