How can we improve PI DataLink?

Setting to allow the omission of error strings in Calculated or Filtered Results

Give the customers either an option or an application setting that allow them to omit error strings from function output. This would allow them to more easily chart results. Some examples of current strings that cause charting problems include, the "[-11101] All data events are filtered in summary calculation" message in PIAdvCalcFilDat/PIAdvCalcExpFilDat and the "Calc Failed" message from PIExpDat.

Note: This was previously Enhancement 26880OSI8.

    In addition to omission of error strings and "Bad Input" values, a customer requested that DataLink should have the function of changing the value. Currently, when I try to overwrite the value where the Pi data call is, I get "You cannot change part of an array" error.
    This is problematic because there are a number of production calculations using pre-built graphs that are based on the calculated columns which use PI raw data. The UserVoice above requests the option of omitting bad inputs, I am requesting that there be an option to change the bad inputs to correct values. This will only be on the clients side. The modified value does not get sent and updated in the data archive.
