The following statements are untrue about ODSs.
-
It is possible to create ODSs without any data fields.
-
An ODS can have a maximum of 16 key fields.
-
Characteristics and key figures can be added as key fields in an ODS.
-
After creating and activating, an export data source is created automatically.
An ODS can be created with zero data fields (just key fields). Both characteristics and key figures are valid key field types. The 16-key-field limit is incorrect (ODS has no such fixed limit). Export data sources must be created manually, not automatically.
To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) It is possible to create ODSs without any data fields.
- This option is incorrect because it is true that it is possible to create ODSs without any data fields. ODSs can be used as a storage container for data without any specific structure or fields.
Option B) An ODS can have a maximum of 16 key fields.
- This option is incorrect. An ODS can have more than 16 key fields. There is no specific limit on the number of key fields that can be defined in an ODS.
Option C) Characteristics and key figures can be added as key fields in an ODS.
- This option is correct. In an ODS, both characteristics (such as customer name, product category) and key figures (such as sales quantity, revenue) can be added as key fields. This allows for flexible reporting and analysis on the data stored in the ODS.
Option D) After creating and activating, an export data source is created automatically.
- This option is incorrect. After creating and activating an ODS, an export data source is not created automatically. If an export data source is required, it needs to be manually created.
The correct answer is A, C. Option A is incorrect because it is possible to create ODSs without any data fields. Option C is correct because characteristics and key figures can be added as key fields in an ODS.
