DataSources to Access Entity Service Attributes  

You can create special DataSources to access language-dependent data of entity services that were modeled with language-dependent attributes. To do this, you use the DataSource name pattern CAF_BW_LD_DATASOURCE_NAME_PREFIX, plus the name of the entity service DataSource.

Example

For the service sap.com/caf.tc/CategoryValueService, the DataSource name used to extract language-dependent attributes could be:

LDE41CategoryValuecaftcfindByM  (CAF_BW_DATASOURCE_NAME_PREFIX = E41, CAF_BW_LD_DATASOURCE_NAME_PREFIX = LD).

This DataSource contains all language-dependent attribute fields: key (record key), parentKey, lastChangedAt (from parent entity object) and lang (locale of attributes text).

In the service sap.com/caf.tc/CategoryValueService, you have the following language-dependent attributes:

○       shortText (com.sap.caf.core.shortText)

○       longText (com.sap.caf.core.longText)

The resulting DataSource has the following structure:

Name	Description	SQL Type	Length
KEY	Record key	VARCHAR	36
PARENTKEY	Key of parent entity object	VARCHAR	36
LASTCHANGEDAT	Last changed date	VARCHAR	30
LANG	Locale (location)	VARCHAR	5
SHORTTEXT	Attribute value defined as shortText	VARCHAR	30
LONGTEXT	Attribute value defined as longText	VARCHAR	60
RECORDMODE	Technical field for generic extractor	VARCHAR	1
