+/**
+  @file
+  @brief validating the mpe_security.sas_group column
+  @details The input table is simply one row from the target table in table
+  called "work.source_row".
+
+  Available macro variables:
+    @li LIBDS - The library.dataset being filtered
+    @li VARIABLE_NM - The column being filtered
+
+
+  <h4> Service Outputs </h4>
+  The values provided below are generic samples - we encourage you to replace
+  these with realistic values in your own deployments.
+
+  <h5>DYNAMIC_VALUES</h5>
+  The RAW_VALUE column may be charactor or numeric.  If DISPLAY_INDEX is not
+  provided, it is added automatically.
+
+  |DISPLAY_INDEX:best.|DISPLAY_VALUE:$|RAW_VALUE|
+  |---|---|---|
+  |1|$77.43|77.43|
+  |2|$88.43|88.43|
+
+  <h5>DYNAMIC_EXTENDED_VALUES</h5>
+  This table is optional.  If provided, it will map the DISPLAY_INDEX from the
+  DYNAMIC_VALUES table to additional column/value pairs, that will be used to
+  populate dropdowns for _other_ cells in the _same_ row.
+
+  Should be used sparingly!  The use of large tables here can slow down the
+  browser.
+
+  |DISPLAY_INDEX:best.|EXTRA_COL_NAME:$32.|DISPLAY_VALUE:$|DISPLAY_TYPE:$1.|RAW_VALUE_NUM|RAW_VALUE_CHAR:$5000|
