Yes, just create a promotion rule and select type "Sales Order Detail". Then choose "Custom rule" and from the New from template, choose the "Flat discount if exceed amt". Change the desired values. In the example template, it shows the amount (100 for purchases exceeding $100 dollars) and the discount to apply (-0.10 means discount by -10%).

Thank you

I did see that but I want to discount by a fixed dollar amount not a percentage.

This way I can limit the amount of discount. What would be the change in the code to discount by say $20.00 for any order over $100.00

You can modify the rule like this. Just change the variable values.

<xsl:transform version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="/">
    <out>
      <discountAmount>
        <!-- Sum up all the sales order details amount and test if exceeds $100 to give a fixed discount of $10 -->
        <xsl:variable name="subTotal" select="sum(in/salesOrder/salesOrderDetails/salesOrderDetail/amount)" />
        <xsl:variable name="minSpend" select="100" />
        <xsl:variable name="fixedDiscount" select="10" />
          
        <xsl:if test="$subTotal &gt; $minSpend" >
          <xsl:value-of select="-1 * $fixedDiscount * in/this/salesOrderDetail/amount div $subTotal" />
        </xsl:if>
      </discountAmount>
    </out>
  </xsl:template>
</xsl:transform>

Thank you Steve

This is exactly what I need
