Error in PipelineManager while creating new payment group

Question

Hi Everyone,
I am  trying to create a new payment group for purchasing an item with the reward points.  i am trying to modify the pipeline flow by overriding commercePipeline.xml.  i have added the following lines of code in that xml.
commercepipeline.xml
<pipelinemanager>
<pipelinechain name="validatePaymentGroup">   
  <pipelinelink name="dispatchOnPGType">
    <transition returnvalue="5000"
      link="validatePointsPG" />
  </pipelinelink>
  <pipelinelink name="validatePointsPG"
    transaction="TX_MANDATORY">
     <processor jndi=
      "/com/mystore/order/processor/ValidatePointsPaymentGroup" />
  </pipelinelink>
</pipelinechain>
<pipelinechain
  name="validatePaymentGroupPreConfirmation">
  <pipelinelink name="dispatchOnPGTypePreConfirmation">
    <transition returnvalue="5000"
     link="validatePointsPGPreConfirmation" />
  </pipelinelink>
  <pipelinelink name="validatePointsPGPreConfirmation"
   transaction="TX_MANDATORY">
     <processor jndi=
      "/com/mystore/order/processor/ValidatePointsPaymentGroup" />
  </pipelinelink>
</pipelinechain>
</pipelinemanager>
when i am starting  the server  getting below error:
ERROR [nucleusNamespace.] Unable to start service "/atg/commerce/PipelineManager": atg.nucleus.ServiceException: CONTAINER:atg.service.pipeline.PipelineInitializationException; SOURCE:atg.service.pipeline.TransitionException: A PipelineLink is already mapped to return code [5000] in the pipelink named [dispatchOnPGType].
when i tried to check the commercepipeline in Dynamo Administration it is showing that the pipelinechain is locked

U have assigned return code 5000 in both chain to ur new pipeline link.
OOTB 5000 is already assigned to invoice chain.
U need to change return code to new unassigned value.Also return code must be added in expected return codes in ValidatePaymentGroupByType component.
Refer this: Oracle ATG Web Commerce - Extending Order Validation to Support New Payment Methods
