Can anybody tell me why I get the following message when I open up a previously saved .twb?:
Loading the data source for the first time. Load time may vary depending on data set size and resources available. Created an extract.
Elapsed time (xx:yy)"
I have been blending data in 2 excel spreadsheets (sizes 99,438 KB and 495KB) but that shouldn't be the reason why this message pops up. It is NOT the first time I'm loading the data because I was doing work without any problems until I hit a point when the queries were taking ages to run. I've tried closing the workbook and, restarting my laptop and opening again.
