Currently, the “import data” function is still under development and can’t support the numeric data with character/string inside, such as NA. So if you have NA values inside the datasets, please use “plan data->create dataset->upload data” procedure.
Another problem you may come across:
if your data is from a calculation instead of measurement, the data type may become decimal (15-16 digits) directly. It may fail the validation if the variable is defined as double.
if you contain -9999 in a decimal (28-29 significant digits) type variable , it will also fail in validation.
If you come across any of this problem, please use ” plan data->create dataset->upload data ” procedure to upload datasets.
