Hi Folks,
you might need to replicate and confirm the following before marking it as a defect.
Take two source ds, sA & sB.
sA has 3 columns, a,b,c.
sB has 3 columns, x,y,z.
In a DataFusion sA is joined to sB to create R, the result ds.
After the R is created, it contains a,b,c,x,y,z.
Next i want to extend sA, i've added a new column in sA call d.
sA now contains a,b,c,d.
After R is rebuilt, in the preview of the ds, we see a,b,c,d,x,y,z, but d is greyed out.
d also dose not appear on the cards.
To resolve this (unexpected behaviour), we need to edit our DataFusion R.
Graphically remove the to source ds, sA and sB, which in turn removes the joins.
Then add back sA, sB, and add the same join again.
Now when previewed, d is no longer greyed.
Additionally d is abailable in the cards.
Rgds,
