I need your help about the creation for a datasource.
I have, with only one datasource, read data in different flat files, these flat files have the same naming convention structure. That is to say, the naming convention is CEEXXRT0001. In this naming convention structure, only XX change has different values according the files.
I know that I have to create a routine for the datasource, but I don’t know how I can do that, somebody can help me ?
