@TNShan
I can see you are using a Dynamic Rename tool and maybe use the option "Take Field Names from Right input"?
The error in red is just as it states, the number of fields of your right input and your current data is not matching.
Hi, thanks for pointing that out, below is the data from my Left and Right. How can I correct it? The Right should be the corerrct one.
hi @TNShan check if the datatype of both the fields are same and if they are same use data cleansing tool to remove the punctuation from the right anchor
