Merging Sequential files

[pkothana]

I am currently working on Datastage 6.0 with Parallel extender. It is required to merge 4 sequential files based on a key value. For ex:

Structure of File 1 : EmpNo, Name
Structure of File 2 : EmpNo, Dept
Structure of File 1 : EmpNo, Age
Structure of File 2 : EmpNo, Salary

I have to merge these files which will have following structure :

EmpNo,Name,Dept,Age,Salary

All files may have different employees. It is required to capture all the employees which are there in any of the file, other fields can be null in that case.

While trying with MERGE Stage or JOIN stage, the final result is only the employees common in all files with the records rejected have following warning message :

Sequential_File_7.DSLink8,0: Field "Name" is null but no null export handling is defined
Note : I have specified all the fields as Nullable

Any help with this simple looking job is highly appreciated.

Thanks a lot in advance.
