From "Explorer" tool view, Navigate to the base standard schema to be derived from. In this case, we use standard schema of FIX 4.4 - FIX44.
Right click mouse to activate the pop up context menu, then click "New Schema".
A "New Schema Dialog" will pop up. Fill in information as shown below:
Note the properties such as "ApplVerID", "ApplExtID" and "CstmApplVerID" are introducted in FIX transport protocol since FIX 5.0 specification.
We give the new schema a name of "US_Equity_PropDesk_44". We also fill in some text information as description and revision information. Note the name of schema must not conflict with other schema names in the repository and must follow the Naming Convention.
After clicking "OK" button, a new FIX schema (derived from standard FIX44) will be created and opened in the document area for editing.
A new node will be added to the "Repository Explorer" tree view as well, under the node of parent schema - "FIX44".
The schema is presented as a tree view. On the tree view user can navigate to schema fields, header and trailer structures and component and message structures.
Note: In the above screen shot, the "Properties" tool windows is also displayed on the right side. "Properties" tool is used in schema editing. It's important to keep that tool window open and visible during schema editing process.
Finally, there's an asterisk sign "*" appended after the schema name in the above display. In Enterprise Manager, the asterisk sign "*" indicates that the resource is either just created or just modified without being saved. Closing Enterprise Manager with unsaved resource will result in a warning window pop up asking to save unsaved works.
In the following chapters, we will walk though customizing the new schema that we just created.
