<mig:menu-info>

<mig:menu type="ons" name="HRDM"/>

<mig:menu type="ux" name="ARD"/>

</mig:menu-info>

<mig:field-details>

<mig:fields existence="nonMap">

<mig:field>

<mig:field-type type="ons">

<mig:ui-field>funcCode</mig:ui-field>

<mig:label>FLT000204</mig:label>

<mig:label-desc>Function</mig:label-desc>

<mig:mandatory>Y</mig:mandatory>
