Error in a view query

Question

Hi,
I'm triyng to create a view but I couldn't due to I have the following error:
ora-00904: esml.sml_obsol_movimientos.cosicltr. Invalid identifier.
The view is:
select obm.cosicltr,
case obm.cosicltr
when 'AL' then count(obm.cosicltr)
when 'LI' then count(obm.cosicltr)
end
from esml.sml_obsol_movimientos obm
group by esml.sml_obsol_movimientos.cosicltr;
Any ideas? The error is in the last line.
Thanks.

It seems to be the day for it. See the first response to Accesing a table of another schema via trigger doesn't work.
You also need to alias the case statement with a column name to create the view.
Warren:
That is a searched case statement and is syntactically valid in 9i and up.
