Use the w_master pfc_Save eventTag(s): PFC

The w_master pfc_Save event will update all "self_updateable" objects. u_dw is self updateable by default but you must of_SetUpdateable(TRUE) n_ds, u_lvs, u_tab and u_tcs objects to enable this feature. Each these self-updatable objects have their own events that will be called by the w_master pfc_Save event. Here is the event sequence that will occur during a pfc_Save

pfc_AcceptText	execute an AcceptText on all self-updating objects
pfc_UpdatesPending	Check if there is any self-updating object that need to be updated
pfc_Validation	extend on the object performs validation on the object level returns SUCCESS if ok, FAILURE otherwise. For non-PFC object, create an user event called ue_validation which returns an integer greater or equals to 0 for SUCCESS.
pfc_UpdatePrep	extend on the window Empty event, use to prepare an update
pfc_PreUpdate	extend on the window or control Empty event more validations if necessary, return SUCCESS to continue the pfc_Save process or FAILURE to abort
pfc_BeginTran	extend on the window Empty event code the transaction beginning, returns SUCCESS to continue the update
pfc_Update	extend on the window Do the update on the self-updating objects. For non-self-updating object, you can code here the update procedure. Returns SUCCESS or FAILURE. If it's a failure, use of_SetDBErrorMsg() to set an appropriate error message (it will displayed by the pfc_DBError error).
pfc_EndTrand	extend on the window Empty event Here you can code the SQLCA.of_Commit() or SQLCA.of_Rollback() depending on the savecode (an event parameter) value.
pfc_DBError	extend or overrride on the window If an error occurs, this event will occur.
pfc_PostUpdate	extend on the window or control Reset update flags on the self-updateable objects
