# CDR075 - Default Serving SID not found

Override is allowed

| Name | Default Serving SID not found. |
| --- | --- |
| Common Cause | No Default serving SID is configured (or it IS configured but cannot be found in the SID table). |
| Common Resolution(s) | Actions you can take to resolve the problem: - Make sure a default Serving SID/BID is specified in Admin Console/ Backoffice Settings/ Rating/ Usage/ Default Serving SID/BID. Also make sure this SID is present in the SID table (see Applications/ Backoffice Management/ Roaming/ SID Maintenance). - The SID table may be out-of-date. Contact IDI BCT to upload any newer version of this table. - If the usage record should be billed anyway, choose Override Rule on the usage record. If this is done frequently, consider a change to Unbillable Rules for this Unbillable Code. Note that ignoring lookup failures can have undesirable downstream repercussions – although some event type processing doesn’t care about Serving SID, in others the Serving SID is fundamental to determining the correct roaming agreement. |
| Details | Certain CDMA-specific usage records require a Serving SID in the usage record in order to rate and discount correctly. In this case, one of the following occurred: - The Serving SID cannot be determined because it is not in the original CDR and a default setting isn’t specified in ***Admin Console/ Backoffice Settings/ Rating/ Usage/ Default Serving SID/BID.*** - A Default Serving SID is configured but it could not be found in the SID table. |
