Hello togehter,

the table relation of "Unit of Measure Code" in "Standard Service Line" should be:
IF (Type=CONST(Item)) "Item Unit of Measure".Code WHERE (Item No.=FIELD(No.)) ELSE IF (Type=CONST(Resource)) "Resource Unit of Measure".Code WHERE (Resource No.=FIELD(No.)) ELSE "Unit of Measure"

and not
IF (Type=CONST(Item)) "Item Unit of Measure".Code WHERE (Item No.=FIELD(No.)) ELSE "Unit of Measure"

Thanks in advanced,
Benjamin
