Hi ,
could you please clarify the statement:
on checking the tables, both columns "project_unique_id" and "previous_project_id" are filled with NULL values
which table? the source table? or which DataFrame? Transform9DF or Transform3DF ?
could you post the schema of these 2 dataframes?
I might be mistaken, but I think that the apply mapping you are using is dropping any field other than "(src) project_unique_id"
so when you trying to join on Transform9DF['previous_project_id']
this field is not found.
thank you
