Attribute Missing Error

Hi,
I'm getting an Attribute Missing Error for a Join operator:

However, the attribute is definitely there:


Any suggestions? I can't seem to find a similar error reported before.
Thanks,
Karim
PS. I tried setting the role before and after the De-Pivot that came earlier. Nothing happened. I tried generating a new attribute called Question_ID based on the Question_ID that already exists. No help.

Fixed it for now by storing the result of the previous process and retrieving it for the following process. A bit of a silly work around, but it does work.0

Hi,Pivot, De-Pivot and Transpose is the other main source. Since every operator only knows the schema, and not the content it cannot calculate the resulting schema for such operations.Best,Martin0

Hi @karim_keshavjee ,this is only a problem, not an error. It occurs because one of the previous operators, does not report that the left hand side key attribute is in the data set. Commonly the cause is a Read Excel or Read CSV operator, where you did not use the import wizard but configured the operator manually.Best,Martin0

Hi Martin,
Nope. I did use the Wizard. There was no problem until I used the De-Pivot operator. After that, it stopped recognizing the attribute.
