Hi - Is there any way to in DataManager when combining two data sources by appending if one data block returns error and the other returns data then for the append to still work and just return the non error data set ?

My problem is that I have multiple files and some times these files are empty and the IT people instead of sending me empty files just do not send the files at all (I know i can just create a manual empty file with the same name , but i want the process to be fully automated)- Thanks Ben
