Determination and allocation of values

Even simple fields are represented as objects, so-called Nullable Values (recognizable by the ending _NV). This makes it possible in the BAdI to differentiate whether a value is to be "zero" or empty. There is also a data object factory for Nullable Values, which is available as an importing parameter in the corresponding BAdIs.

ExampleMeaning
Document_value_as_nv =
im_nullable_value_factory->dec_15_2( 0 ).
Value is 0.00.
Document_value_as_nv =
im_nullable_value_factory->dec_15_2( ‘15.23’ ).
Value is 15.23.
Clear document_value_as_nv.instance is "zero"/null and the value is not interpreted.
