# CDR015 - Cellsite lookup failed

Override is allowed

| Name | Cellsite lookup failed. |
| --- | --- |
| Common Cause | The serving cellsite in this usage record is invalid. |
| Common Resolution(s) | Actions you can take to resolve the problem: - This cellsite may have been recently put into service. ***Right-click*** the SPUN record, choose ***View Event Details***, and find the raw cellsite information (***Serving LAC*** and ***Serving CI*** in GSM, ***Serving CLLI*** in CDMA). This did not resolve to an entry in the cellsite table. If this is a new cellsite, use Admin Console ‘Cellsites’ to add the new cell site. - If this rarely occurs, the CDR may be bad or malformed. If so, it can be left alone (it will eventually age and no longer be visible) - or it can be purged immediately if desired. - 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 including rating and discounting failures and poor invoice presentation. |
| Details | Certain network-specific usage records require cellsite information in the usage record in order to rate and discount correctly. The cellsite in each such record must be known to CostGuard. In this case, the cellsite in the CDR could not be found in the cellsite table. |
