Diagnosis
You tried to assign an invalid type to the DataSource. The followingtypes are valid:
'MSD' for DataSources that potentially extract attributes.
'TEXT' for DataSources that potentially extract texts.
'TRAN' for DataSources that potentially extract transaction data.
'HCAT' for DataSources that extract hierarchy catalogs.
'HNOD' for DataSources that extract the nodes of a hierarchy.
With 'potentially', we mean that, in addition to the usual way in whichdata is used, it might perhaps be necessary to regard attributes astransaction data. In a HR scenario, for example, you might want tointerpret the attributes for an employee as transaction data.

System Response
The DataSource cannot be saved as it is now.

Procedure
Assign the DataSource to a valid type.
