Reintrospecting SAP BW
Because each SAP BW data source contains resources that are unique to it, it is best to follow a few special steps when you reintrospect to make sure that you can see all expected metadata within Studio.
If you removed any SAP BW resources from the Studio view of the SAP BW data source metadata, reintrospection restores those resources to the Studio resource tree.
Note: If you reintrospect an SAP BW data source, keep the descriptive/technical name choice originally used for that data source. If you change it, results are unpredictable.
To reintrospect SAP BW
From Studio, open the SAP BW data source.
|
1.
|
Click ADD/Remove Resources. |
|
2.
|
Select one or more schemas that you want to introspect or reintrospect. |
Avoid using the Find field during introspection of SAP BW data sources. TDV cannot load all of the SAPBW metadata before introspection. Attempts to use the introspection Find feature can result in SAP BW database service interruptions.

Introspecting Attributes with Duplicate Descriptive Names
To include attributes with duplicate descriptive names while introspecting the datasource:
Open this properties file using your favorite text editor:
<TDV_install_dir>\apps\dlm\app_ds_sapbw\conf\product.properties
|
8.
|
Add/edit the following property: |
sapbw.introspector.includeKeysInColumnNames=true
Setting this value prepends the technical name to the descriptive names.
|
10.

In your data source properties, select the advanced introspection option, "Display Technical and Descriptive Names, Use Technical Names in TDV Resource Namespace". |
