If you know what package.procedure(s) you are interested in, you can just
search for references to 'package.procedure' in xxx_SOURCE view.
select name, type, line, text
from user_source
where lower(text) like '%package.procedure%'
and type = 'TRIGGER'
You can further limit by using a subquery finding all dependencies on the
package from triggers.
It is valid to leave spaces between package, period, and procedure name; if
that is likely, you might want to use a regex match rather than plain old
LIKE.
It is very rare (not completely unknown) for the package.procedure to be
split across a line break (I'd regard that as a coding standards failure) eg
IF X > Y THEN
Package ,
Procedure (a,b,c);
END IF:
Finally; this mechanism picks up comments (and commented out calls). You can
fairly easily exclude single line comments (--). It's more of a pain to
exclude multiline comments (/* ... */). You can decide whether this is a big
issue or not...
