I've got over 90 APs installed and displayed on WCS but with one particular building, neither of the two floors will display heatmaps. Instead there is an error message that says "Error(s): You must correct the following error(s) before proceeding: Error: Some of the AP's RF Prediction is not yet computed. Please go to the AP placement page and place the APs properly, specify the correct antenna and then recompute the RF prediction." This is a new install so it hasn't yet worked.
I've done everything I can think of including deleting and recreating the building and its floors. I don't see anything in the bug toolkit or other postings or release notes. I even tried changing the antennas to "other" and then back again.
I'm running the latest WCS code 4.1.83 base+location and WLC code 4.1.171.
I thought I'd close this off with the solution I found.
I ended up deleting the APs from WCS and then letting them be discovered again. To do that I had to power them down. It took several minutes for WCS to recognize they were down and then a few minutes to no longer have the check box greyed out. You need the check box so you can select the AP and delete it. Then I powered up the APs. I put them on the map with default antenna settings to make sure the heatmap would show. Then I modified the antenna settings.
I think the WCS database somehow got corrupted when I originally added the APs for this building. The corruption was likely in the fields that define the 802.11a antenna type and orientation.
I hope this will be of help if and when others encounter this.
