Hi,
OnSubjobOK and OnComponentOK are trigger links, which can link to another subjob.
What is a subjob?
A subjob is a self-contained subset of a larger Job, composed of components and links.
The following diagram shows a Job with three subjobs: see pic
The main difference between OnSubjobOK and OnComponentOK lies in the execution order of the linked subjob. With OnSubjobOK, the linked subjob starts only when the previous subjob completely finishes. With OnComponentOK, the linked subjob starts when the previous component finishes.
The execution order of subjobs linked by OnComponentOK is within the exectuion cycle of the previous subjob. In this example, subjob 2 starts when tLogRow_1 finishes; subjob 3 starts when both subjob 1 and subjob 2 end, because subjob 2 runs within the execution cycle of subjob 1.

Hi Sabrina,

As with the explanation to the subjobOk and componentOk, I have my flow executed as if I was using subjobOk, although I am using componentOk. Please find the attached.

I am reading CSV file and for every line in the CSV file, I want the read MongoDB for matching value from the CSV record. But the read Mongo is invoked only for the last CSV record in the file.

Here is the output: MongoId is printed only once while there are 2 matching records for each row of CSV file.
