Hello i'm trying to build a ETL system, that read from the database the mapping (where i've got the source,destination and transformations info) the code down written is the parent code, that loads the child, and defines its configurations.
but i get a wierd problem... the destination configuration doesn't stick. the source absorbs the configuration but not the destination.
when I save, the dataflow gets deleted on the saved .dtsx

what am I doing wrong? i've started this code with an example of building a package from scratch.
any help is welcome, Thanks!
