  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>
  <xsl:key name="name" match="service" use="name"/>
  <xsl:template match="service_list">
    <serv_list>
      <xsl:for-each select="service[generate-id(.) = generate-id(key('name', name))]">
        <xsl:call-template name="group">
          <xsl:with-param name="node-set" select="key('name', name)"/>
        </xsl:call-template>
      </xsl:for-each>
    </serv_list>
  </xsl:template>
  <xsl:template name="group">
    <xsl:param name="node-set"/>
    <final_serv_list>
      <xsl:copy-of select="$node-set[1]/name"/>
      <xsl:copy-of select="$node-set[1]/cr_case_id_fk"/>
      <xsl:for-each select="$node-set[position() &lt;= 6]/claim_amount">
        <xsl:element name="{concat(name(), '_', position())}">
          <xsl:value-of select="."/>
        </xsl:element>
      </xsl:for-each>
      <xsl:if test="count($node-set) &lt; 6">
        <xsl:for-each select="(document('')//*)[position() &lt;= (6 - count($node-set))]">
          <serv_list/>
        </xsl:for-each>
      </xsl:if>
    </final_serv_list>
    <xsl:if test="count($node-set) > 6">
      <xsl:call-template name="group">
        <xsl:with-param name="node-set" select="$node-set[position() >= 7]"/>
      </xsl:call-template>
    </xsl:if>
  </xsl:template>

or if the services are always ordered as they are in your example

  <xsl:template match="service_list">
    <serv_list>
      <xsl:apply-templates select="service[1]"/>
    </serv_list>
  </xsl:template>
  <xsl:template match="service">
    <xsl:variable name="group" select=". | following-sibling::service[position() &lt; 6][name = current()/name]"/>
    <final_serv_list>
      <xsl:copy-of select="name"/>
      <xsl:copy-of select="cr_case_id_fk"/>
      <xsl:for-each select="$group/claim_amount">
        <xsl:element name="{concat(name(), '_', position())}">
          <xsl:value-of select="."/>
        </xsl:element>
      </xsl:for-each>
      <xsl:if test="count($group) &lt; 6">
        <xsl:for-each select="(document('')//*)[position() &lt;= (6 - count($group))]">
          <serv_list/>
        </xsl:for-each>
      </xsl:if>
    </final_serv_list>
    <xsl:apply-templates select="following-sibling::service[count($group)]"/>
  </xsl:template>

Hope this helps,
