Tmap result populates blank values for one table

[Anonymous]

Hi,

My Tmap is input of 3 tables joined together. all tables are joinied by unique match and left outer join.

Somehow after my join, when I output my result, my last table populates blank(no) values for all column.

what could be the cause?

If you are using outer join and no match from lookup it will return null values. Please check join is corret and has matched records in lookup table.
