Enrique,

The business object in CBizObjMaintenanceForm is actually based on KBizObj.

>IF kbizobj class doesn't have the lSaveChildOnSaveParent Property, which code recommend me to save child records.>

If you have set up a parent/child relationship between business objects, the child business object's records will automatically be saved when the parent businsess object's record is saved.

> When you call the Form Save Method, you use transactions for do it?

The Form Save method doesn't do any saving itself...rather, it calls the primary business object's Save() method.
