When Keep Existing Values is selected, it will retain the original secondary Keyword Values and a new instance will be added containing the AutoFill Keyword Set data.
Note:
When Expand All Matching Instances is configured for the selected AutoFill Keyword Set, Keep Existing Values is selected by default.
Note:
It is recommended that you do not use the Keep Existing Values option with Chart-based, MRN-based, or MPI-based AutoFill Keyword Sets.
CAUTION:
The Keep Existing Values option is not supported in the Classic Client interface.
