Hello All,
I am trying to generate multiple records from single input.
suppose i have 10 records in my input and on that i have 4 set of repeated records then i have to generate 4 files with dynamic file names which i generating in compute. So my flow is like
MQi/p>>>compute>>>fileout(wired to in)
I am able to generate 4 files and placing them in local ftp location after that the while loop ended and go return true statement and again go to fileo/p node and failling their because empty file name error. My question is how to stop the flow without going to fileo/p after placing 4 file. can any one help me to figure it out.
Thanks.  |

Did you use a PROPAGATE statement inside your while loop?

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Put RETURN FALSE at the end of the Compute node not RETURN TRUE.
The Compute module is a function that returns a Boolean. If true, it propagates the OutputRoot to the Out terminal (which is probably empty given your logic). If false, it does not.

Hello Vitor and smdavies99,
Yes I tried with the propagate and RETURN FALSE before posting this in blog but, no use.
Now i used if condition along with PROPAGATE and RETURN FALSE now working. 
.
.
.
IF OutputLocalEnvironment.Destination.File.Name IS NOT NULL THEN
PROPAGATE;
END IF;
END;
END MODULE;
Thanks a lot. |

You should reconsider using a WHILE loop - especially if you're using [n].
Use a FOR loop. It's much easier and safer and less coding.
Your IF statement doesn't necessarily make sense. If you know when you are populating OutputLocalEnvironment.Destination.File.Name, then you should be doing your PROPAGATE from there.
Perhaps if you showed the entire compute module, - or at least most of it removing any large set of SET statements that work with the *Root trees for business data - then you could get more targeted help that is better suited to your code. |
