How Siebel CRM Desktop Reuses, Modifies, and Updates Metadata Files
Siebel CRM Desktop creates a relationship between each customization package and a collection of metadata files, and it can use each metadata file with more than one customization package. You cannot modify the metadata file after Siebel CRM Desktop creates a relationship between this metadata file and an active deployment package. You can export, modify, and then reimport the metadata file to create a new metadata file. Although multiple customization packages can reference the same metadata files, one or more metadata files typically use different customization packages that include different information.
For example, the Microsoft Outlook Sales Representative responsibility is different and separate from the Microsoft Outlook Sales Manager responsibility. Although you can create a relationship between an existing responsibility and a customization package, it is recommended that you create a new responsibility. This configuration provides you with more control in determining the users that Siebel CRM Desktop uses with a customization package.
