Dear Sandu, in most cases, the problem you mention can be solved by adding an indicator variable called _EMBEDDED to the basemap dataset. This variable should take value 1 if the corresponding polygon is completely enclosed in another polygon, and value 0 otherwise. For details, please see the -spmap- help file ("Spatial data format").
