SavePartialChanges (dataset-handle, Object)

Purpose:	Saves partial changes to the Business Entity Dataset
Notes:	Saves only those fields from the provided Dataset. Does fetch the
	complete dataset first, then applies changes from the provided
	dataset to the complete dataset and saves this using SaveChanges.
	Relies on ROW-STATE in the partial dataset as well! A separate method
	may be added in the future, that only expects current values from the
	passed in ProDataset
	When multiple records are provided in the partial dataset, currently
	each record is processed alone
	For simplicity of the partial dataset, we do not expect this dataset to
	have indexes defined. However, we do expect that the partial dataset
	contains the columns of the primary unique key of the business entity
	dataset columns
	Flow of actions:
	- Fetch the whole Dataset Records
	- Manipulate the "before"
	- Manipulate the "after"
