Append Querry DB2 and Txt File not working

Hi Icey  thank you for your idea I was able to bypass the issue since it was all about performance. By adding the DB2 source, the performance of loading time for the data deteriorated quite significantly. So What I did was that I refreshed the model before the data entered the DB2 and appended query with .txt.

Since it had 0 rows on DB2 the appending worked fine and then I moved the model to reporting server which has much higher computing power then my Laptop and scheduled a refresh there with the full DB2 data. Now it is working fine as the update is happening on the server.
