If several identical objects exist within a fragment definition graph (identical attribute value for AT_OBJNAME_INTERN), you need to specify a unique AT_NODE_ID object attribute in the fragment definition to differentiate between the objects. In the attribute mapping file, instead of the value of the AT_OBJNAME_INTERN object attribute you should specify the value of the AT_NODE_ID object attribute.
Example
Fragment definition:
The fragment definition contains two Order is created end events.
...
<graph id="CHPFLICHT_AUFTRAG_ANLEGEN">
<node id="4" type="OT_EVT">
<attribute type="AT_OBJNAME">Order to be created</attribute>
<attribute type="AT_OBJNAME_INTERN">SAP.AUFT_ANZU</attribute>
</node>
<node id="5" type="OT_FUNC">
<attribute type="AT_OBJNAME">Create order</attribute>
<attribute type="AT_OBJNAME_INTERN">SAP.AUFT_ANLEG</attribute>
</node>
<node id="42" type="OT_RULEOR"/>
<node id="6" type="OT_EVT">
<attribute type="AT_OBJNAME">Order is created</attribute>
<attribute type="AT_OBJNAME_INTERN">SAP.AUFT_ANGELEGT</attribute>
<attribute type="AT_NODE_ID">End event 1</attribute>
</node>
<node id="7" type="OT_EVT">
<attribute type="AT_OBJNAME">Order is created</attribute>
<attribute type="AT_OBJNAME_INTERN">SAP.AUFT_ANGELEGT</attribute>
<attribute type="AT_NODE_ID">End event 2</attribute>
</node>
<edge type="CXN_FOLLOWS" source="4" target="5"/>
<edge type="CXN_FOLLOWS" source="5" target="42"/>
<edge type="CXN_FOLLOWS" source="42" target="6"/>
<edge type="CXN_FOLLOWS" source="42" target="7"/>
</graph>
...
Attribute mapping:
At the two Order is created end events, attribute mapping generates a PPM attribute AT_ID with a different value:
...
<attributemapping>
<objectattributes objectname="End event 1" graphid="AUFTRAG_ANLEGEN">
<attribute ppmattributetype="AT_ID">
<value>This is the first end event</value>
</attribute>
</objectattributes>
<objectattributes objectname="End event 2" graphid="AUFTRAG_ANLEGEN">
<attribute ppmattributetype="AT_ID">
<value>This is the second end event</value>
</attribute>
</objectattributes>
</attributemapping>
