I am currently having an issue related to Meta Point. Appreciate your guidance.
I had do the following setup:
- create 1 virtual data source & 1 meta data source.
- create 10 datapoints in virtual data source.
- create several datapoints in meta data source. My script will use the datapoints created in virtual data source. I had also included TIMESTAMP = XXXX.time so that the timestamp of the meta point is the same as virtual point.
- create excel report to download the 10 datapoints in virtual data source and a few datapoints in meta source.
- run the excel report
After download the excel report from Mango, I had included the formulas manually (same formula in the script for meta datapoints) in the excel report to check if the meta points produced the same results as the formulas I had created in the excel report.
I had realized that the figures in meta points do not tie to my manual calculated figures occasionally.
I had checked and realized that the meta point timestamp differs occasionally and this may be the trigger point for the variance. I do not know why the timestamp for meta point will differ (for example, 16:51:11) occasionally from the standard 16:xx:13 which is the same timestamp for virtual datapoints.
Historical for one of the meta point:
