Multiway Merge Join

Hello All,

I wanted to know how Multiway Merge Join step works. so I designed this sample transformation:
Capture1.jpg


The properties of the step were configured as follows:
Attachment 11838

The structure of files are as follows:
File1 : Comp1,f1,f2
File2: Comp2,f3,f4
File3: Comp3,f5,f6
File4: Comp4,f7,f8

I have some matching data in Comp field in all 4 files and have sorted the data on the corresponding Comp field before inputting it to Multiway Merge Join step
I want in the Inner join output Comp1,f1,f4,f6,f8

I am getting the following error:
Capture3.jpg

Am I doing something wrong?

Regards,
Bishnu
