When uploading your rate request, the error show: Line item 1 conflicts with existing rate. This error can be caused by two different problems.
The Rate Request (RR) with the RATE for the timekeeper in line 1 was 'Approved' or is 'Pending Client Approval' with dates that overlap the new rate request.
The old "Approved" rate request should be deleted and then you should be able to create the new one. If the rate request is "Pending Client Approval" you will have to wait until it is "Approved" or "Rejected". Review the list of Rate Requests by viewing the Timekeepers > Rate Requests page. Note that deleting an "Approved" rate request does not delete the approved rate.
This could also be caused by two lines with the same timekeeper with overlapping information in the file.
Check if there are two or more lines with the same timekeeper in your file and remove the duplicate lines.
