APAR status

  • Closed as program error.

Error description

  • The initialisation order of message flow nodes is unspecified so
    a BIP3451 warning may occur if a SAPReply node attempts to start
    before any SAPInput node in the same flow has had a chance to
    start.
    
    Additional Symptom(s) Search Keyword(s):
    

Local fix

  • Manually editing the .msgflow or .subflow file to ensure that
    the SAPReply node's definition appears after that of a SAPInput
    node, and that the unique ID for the SAPReply node is
    lexicographically after the unique ID for a SAPInput node
    should force the SAPInput node to start before the SAPReply
    node, but this is not guaranteed.
    

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    All users of the SAPInput and SAPReply nodes in IBM App Connect
    Enterprise v11.
    
    
    Platforms affected:
    MultiPlatform
    
    ****************************************************************
    PROBLEM DESCRIPTION:
    The initialisation order of message flow nodes is unspecified so
    a BIP3451 warning may occur if a SAPReply node attempts to start
    before any SAPInput node in the same flow has had a chance to
    start. For example:
    
    BIP3451W: SAPReply node 'mySAPReplyNode' in message flow
    'mySAPFlow' has been deployed to integration server 'myIS' that
    has no SAPInput node.A SAPReply node replies to a BAPI call that
    a SAPInput node receives. If no SAPInput node is present, a
    SAPReply node does not have a BAPI request to which to
    respond.The message flow will deploy but an error will be thrown
    if a message reaches the SAPReply node. Add a SAPInput node to a
    flow in this integration server and re-deploy.
    
    This message should only be issues if there are no SAPInput
    nodes in the same flow.
    

Problem conclusion

  • The BIP3451 warning will now only be issued by a SAPReply node
    if there are no SAPInput nodes registered after every message
    flow node has been initialized.
