Hi, This is just not possible to merge 2 flows issued from a tReplicate or a tMap in the same subjob where they have been created. You need store the tAggregateRow result into a tHashOutput or a file if you prefer. You also need to replace the tMySQLOutput by a tHashOutput. Then, start a new subjob by a tHashInput associated to one of the tHashOutput connected to the tFileList component by an onSubjobOk trigger. Finally, connect this flow to a tMap. Connections a 2nd tHashInput associated to the other tHashOutput as a lookup and push the result from the tMap to your tMySQLOutput. Hope this help.
