Answer / afnas
Both(COLHDG & ALIAS) are used to identify fields.COLHDG &
ALIAS is the Description of fileds.the diference is that in
ALIAS we can access data based on that ALIAS name,while
COLHDG is not allowed.suppose in PF field name as
DES78,give ALIAS as Description78,then user can access data
from using Description78.
