DataSources to Access Business Object Node Attributes  

CAF provides a DataSource for each business object node to access its attributes. It is automatically generated by CAF. For most business object node attributes, there is a field in the DataSource. Attributes of type BASE64BINARY or HEXBINARY and language-dependent attributes are not a part of the DataSource. For attributes of type DATETIME, CAF defines three fields in the DataSource:

·        DATE

·        TIME

·        BIGINT (containing the time in milliseconds)

Example

We have a business object node sap.com/school/Teacher. It has the following attributes:

Name	Type
key	caf.core.services.Id
createdBy	caf.core.services.UserId
createdAt	caf.core.primitive.DATETIME
modifiedAt	caf.core.primitive.DATETIME
createdBy	caf.core.services.UserId
name	caf.core.primitive.STRING
age	caf.core.primitive.INT

 

The DataSource that CAF would provide for this business object node would contain the following characteristics: (assume that CAF_BI_DATASOURCE_NAME_PREFIX = E41)
