Key value in tMap

Hi All,


In the following attachment we are maintaining key value in both input and output, Can someone please explain why we should use key value here and if we are not using the key value then what is the impact while copying the data from source to destination and etc....

Re: Key value in tMap

Can you rephrase that please? I cannot work out what it is you are asking. Your screenshot shows you simply passing each column value from input to output (there is little point using a tMap for this).
