The column "Industry SIC" is rename to "Primary Industry Code" in presentation layer and old name mentioned in Alias.

Reports are already developed using alias name. while generating those reports getting below error eventhough name is mentioned in alias.

Hi,

you don't have to change anything in the reports when you alias a column in the presentation layer, it just works without a rewrite.

So you either need to go back to the prechanged version of the report(s) or refresh the field(s) in question in the report.

Can you also share a screen of the Presentation layer (the alias) as well?

As Robert highlighted, you do not have to do anything post creating a alias in Presentation Layer.

Hi SonPat,

"Primary Industry Code" is having alias name as "Industry SIC" as per below screenshot. Still getting error mentioned above for same column.

Thanks

Does the alias have a trailing space? Just looking at obvious points where the lookup will fail ...

It's looking up Industry."Industry SIC". Your Presentation Column has a FQN (fully qualified name) of "Primary Industry"."Industry Code" if you take into account the table name. Is the table aliased as well?

Hello,

Your Table name from the initial screen shot is "Industry"

But, from the new screenshot, you are referring to table "Primary Industry"

As highlighted by Christian Berg, I think this is causing the problem. Have you renamed the table as well...?

Hi All,

Yes the table name was not aliased. Its working fine now after giving alias name to the presentation table.

Thanks for all your help and Support.

Good to hear. Watch out for aliases - they are a huge pain in the long run and make maintenance and lifecycle-management a real chore since no one knows which combination of "name"."alias"."name" or "alias"."alias"."alias" or "alias"."alias"."name". etc etc etc gets used and where.
