The following example shows how to configure DDM settings for the address field of the Customer table, such as the D: default mask and the #DDM_See_secadmin authorization tag using the setDDMConfig() method:
USING OpenEdge.DataAdmin.DataAdminService FROM PROPATH.

DEFINE VARIABLE service AS DataAdminService NO-UNDO. 
DEFINE VARIABLE lResult AS LOGICAL NO-UNDO.

service = NEW DataAdminService(LDBNAME("DICTDB")).
lResult = service:setDDMConfig("customer","address","D:","#DDM_See_secadmin").
