Ariba® Contract Management 9r1 and Ariba® Sourcing 9r1:  Some Money fields in the Ariba site do not display decimal places by default. The precision property of the field governs this behavior. To change the number of decimal places that display for the field, you can customize the Ariba Markup Language (AML). Using the Contract Workspace Amount field as an example, you can add the linked ContractsExt.aml file to an extension file and place it in the file structure of the site. Include it in the Upstream \Server\config\variants\Plain
\extensions\
directory. If this directory does not exist, please create it.

You can run the checkmeta command to ensure that no conflicts with the change exist. After placing the AML file in this location, restart the server to make the change effective.
