This message may appear while TestComplete is saving data of a tabular object to a Table element. It informs you that TestComplete could not store some of the object’s data. This can happen, for example, if that data is not Variant-compatible (that is, it is neither numbers, strings, dates nor boolean values) or if you have selected too many rows or columns to store. In the latter case, you can reduce the number of rows and/or columns to be stored and try retrieving the object data again.
