Loading three files with different employee types to build a model
I have three files of employee types.
File 1 has type A employees responses which I need to load through crosstable.
File 2 has type B employees responses which I also need to load into the model through crosstable.
File 2 has type C employees responses which some are similat to type B and has to also be loaded into the model through crosstable
These type A , B & C employees have different responses.
My challenge is how do I load all of them into the model through APPENDING. EmployeeNo is the only field common on three files however employees are distinct in 3 files.
