HI!
I have a message flow that needs to transform some data, then always write it to queue A, create a new message for queue B (based on parts of the original message) but only write it to queue B if certain conditions are true. I have the output of my transformation node wired to queue A and to a compute node to format the new message for queue B. How would I code the compute node to not write to queue B if the conditions are met, but not throw an error? Also , my code is always writing the same message that goes to queue A and not my new created message.
Thanks for any help anyone can provide!!
Here is the code so far in my compute node to format the new message to go to queue B:
SET OutputRoot = InputRoot;
-- Enter SQL below this line. SQL above this line might be regenerated, causing any modifications to be lost.
If ((InputRoot.XML.CreateJob.DataArea.Job.WorkCodeUDFS.WorkCodeUDF[13] = 'Y') and
(InputRoot.XML.CreateJob.DataArea.Job.WorkCodeUDFS.WorkCodeUDF[12] > 0) and
(InputRoot.XML.CreateJob.DataArea.Job.WorkCodeUDFS.WorkCodeUDF[12] IS NOT NULL))
then
SET OutputRoot.XML.CreateJob = NULL;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.ApplicationArea;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.ApplicationArea.Sender;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.ApplicationArea.Sender.Component;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.ApplicationArea.Sender.Confirmation;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.ApplicationArea.Sender.AuthorizationId;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.ApplicationArea.CreationDateTime;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.ApplicationArea.BODId;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.DataArea;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.DataArea.REQ_TYPE;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.DataArea.REQ_CODE;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.DataArea.PREMISE_NO;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.DataArea.RECORD_DATA;
CREATE FIELD OutputRoot.XML.ATLAS_XY_QUERY.DataArea.RECORD_DATA.EXTERNAL_ONE;
SET OutputRoot.XML.ATLAS_XY_QUERY.ApplicationArea.Sender.Component = 'MDS XY Query';
SET OutputRoot.XML.ATLAS_XY_QUERY.ApplicationArea.Sender.AuthorizationId =
'ODL Create Job';
SET OutputRoot.XML.ATLAS_XY_QUERY.ApplicationArea.CreationDateTime = CURRENT_TIMESTAMP;
SET OutputRoot.XML.ATLAS_XY_QUERY.ApplicationArea.BODId = UUIDASBLOB;
SET OutputRoot.XML.ATLAS_XY_QUERY.DataArea.REQ_TYPE = 'PREMISE';
SET OutputRoot.XML.ATLAS_XY_QUERY.DataArea.REQ_CODE = 'COORDINATES';
SET OutputRoot.XML.ATLAS_XY_QUERY.DataArea.PREMISE_NO =
InputRoot.XML.CreateJob.DataArea.Job.WorkCodeUDFS.UDF[13];
SET OutputRoot.XML.ATLAS_XY_QUERY.DataArea.RECORD_DATA.EXTERNAL_ONE =
InputRoot.XML.CreateJob.ApplicationArea.BODId;
End if; |

To exit a compute node without propogating anything to the output (and cause the flow to stop processing further, unless other paths are being processed), add "return false;" to your compute node in the appropriate place. |

LisaB,
It is quite simple. Wire your transformation node, located before the queue A node to a filter node and to queue A. In this filter node you can ask for the conditions to met. Now wire the true terminal to a compute node where you will build the message for queue B and wire the out terminal to queue B node.
