How to duplicate the dataset?

[Anonymous]

Here I have a request to duplicate the dataset:
the main table has 2 columns neet to join the same lookup table,
it's easy to load the lookup table twice then use tMap join, but I feel there must be a better way:
I am trying to use tReplicate to create two copy of same dataset then use tMap to join,
but tMap only accept one output from tReplicate.

anybody have the experience?
Thanks,

Please have a look at below screenshot, the black solid line can not attach to tMap.
