Centralizing File Positional metadata

If you often need to read data from and/or write data to certain positional files, you may want to centralize their metadata in the Repository for easy reuse. File Positional metadata can be used to define the properties of tFileInputPositional, tFileOutputPositional, and tFileInputMSPositional components.

The New Positional File wizard gathers both file connection and schema definitions in a four-step procedure.

To create a File Positional connection from scratch, expand Metadata in the Repository tree view, right-click File positional and select Create file positional from the contextual menu to open the file metadata setup wizard.

To centralize a file connection and its schema you have defined in a Job, click the icon in the Basic settings view of the relevant component with its Property Type set to Built-in to open the file metadata setup wizard.

Then define the general properties and file schema in the wizard.

The new schema is displayed under the relevant File positional connection node in the Repository tree view. You can drop the defined metadata from the Repository onto the design workspace as a new component or onto an existing component to reuse the metadata. For further information about how to use the centralized metadata in a Job, see Using centralized metadata in a Job and Setting a repository schema in a Job.

To modify an existing file connection, right-click it from the Repository tree view, and select Edit file positional to open the file metadata setup wizard.

To add a new schema to an existing file connection, right-click the connection from the Repository tree view and select Retrieve Schema from the contextual menu.

To edit an existing file schema, right-click the schema from the Repository tree view and select Edit Schema from the contextual menu.
