Description
The HasCurrentRowValue and HasProposedRowValue functions
can be used in the IngrPreRowUpdate script hooks to determine if there are
values available for a given field. Using these methods prior to calling
GetCurrentRowValue and GetProposedRowValue can avoid run
time errors. The HasCurrentRowValue and
HasProposedRowValue functions check two aspects. First, if there is a
Current or Proposed row available. Secondly, if that row contains the column name that is
passed in as an argument. These functions do not test if the column has value or not. The
GetCurrentRowValue and GetProposedRowValue can be used
to check the column value for null values.
