Attachments tab
Bind an external piece of information, or attachment to the transformation. You can also remove an attachment
from an object, override an attachment binding’s default value, or change the position of a bound attachment. To
override the value of the attachment you have moved to the Selected Attachments grid, double-click the Value
field of the target attachment. ER/Studio opens the Value Override Editor or a list depending on the attachment
datatype. Attachments are created in the Attachments folder of the Data Dictionary and must be applied to the
default before they will display on this tab.

Data Lineage Workflow
Documenting Table/Entity Data ETL
Use the Data Lineage tab of the entity or table editor to document how often the table/entity data is sourced and when
it was last sourced. Once you have created data movement rules in the Data Lineage Explorer, you can apply these
rules to the selected table/entity. You can associate as many data movement rules as you want to the table/entity. You
can report data movement rules when creating reports, generating SQL or XML Schema, or Metadata is exported.
Document table data movement
1 From the Data Model tab, navigate to and then double-click the table/entity whose data lineage you want to
document.
2 In the Table Editor, click the Data Lineage tab.
3 Complete the Data Lineage dialog as required and then click OK to exit the editor.

Data Lineage Workflow
Documenting Column/Attribute ETL
At the column/attribute level, you can document how data is transformed as it moves from one system to another, by
adding transformation logic for source/target attribute mapping. You can map multiple source/targets to one
column/attribute in the physical/logical model.
You can register the same source/target or physical model more than once for a given physical model. For example, in
the Adventure Works.dm1 model, you can register the Adventure Works physical model to the Adventure Works DW
physical model as a direct source AND direct target if the data warehouse is used for analytical reporting and to
perform some data cleansing. Additionally, you can also register the Adventure Works physical model to the
Adventure Works DW physical model as both a secondary source and direct source.
Document column/attribute data sources
1 From the Data Model tab, navigate to and then double-click the table/entity whose data lineage you want to
document.
2 In the table/entity editor, select the column or attribute to document and then click the Data Lineage tab.
3 Click the Direct Sources tab.
4 Click Edit.
