To work with Mapping Analyst for Excel, use the following process:
A business analyst creates a mapping specification based on the Standard mapping specification template.
The business analyst enters the source and target metadata on the Models worksheet.
The business analyst uses Microsoft Excel to connect the source and target ports and develop expressions, joins, lookups, filters, and rules.
A PowerCenter developer uses the Repository Manager to import the mapping specification. The PowerCenter Repository Service creates the PowerCenter objects.
The PowerCenter developer completes the PowerCenter mapping in the PowerCenter Designer.
A PowerCenter developer can also use the Repository Manager to export PowerCenter metadata to a mapping specification.
You can use Mapping Analyst for Excel to import or export metadata. However, Mapping Analyst for Excel does not support a combination of exporting, editing, and importing in a single development process. For example, you export a PowerCenter mapping to Microsoft Excel, edit the metadata in Microsoft Excel, and then import the mapping specification back to PowerCenter. The imported mapping might contain inconsistent metadata.
