I use data loader in production mapping to merge features into a single .gdb. My problem is, data in certain fields become blanks. These fields (from the source gdb) used to have values but onced loaded into the target gdb, its gone. I had the schema properly exported from source gdb and imported into target gdb and validated it. Everything seems to worked well without errors until i have a look at the .gdb. Wondering did i missed something here.
