hi,
the reason is that you read data flow that 's not already finished.
It's due to the fact that you read data in parallel. (the green component)
use trigger to schedule processes.

The problem is the timestamp when you start your 3. subjob.
Change the OnComponentOk triggers to OnSubjobOK starting at the subjob start components.
tMysqlInput_1 -- OnSubjobOk --> tMysqlInput_2 ---- OnSubjobOk ---> tBufferInput (your last subjob)
On of your first subjob finished before the second finished and thats why your HashInput is not initialized.

It worked when i moved the triggers to the start of the subjobs.
Thanks
