Trying to find hard coded schema names by chance?
For GEL scripts you'll primarily want to be looking here:
select script_text from cmn_custom_scripts;
In case it's been put into a process script's parameters, that could be here:
select param_value from cmn_custom_script_params;
If you're unlucky to have used such terms in your pre/post conditions somehow, check here:
select expression from odf_filter_expressions;
And one other likely place to find this term if it is a schema name, will be in NSQL queries, which you can check here:
select nsql_text from cmn_nsql_queries;
Hope that was what you were after. If you need to stitch together the cmn_custom_scripts (gel scripts) back to a process design, it would go something like this (but I won't get to double-check this until the morning so consider this an attempt on the fly):
select p.process_code, step.step_code, action.action_code, script.script_text
from bpm_def_processes p
join bpm_def_process_versions pv on p.id = pv.process_id
join bpm_def_stages stage on stage.process_version_id = pv.id
join bpm_def_steps step on step.stage_id = stage.id
join bpm_def_step_actions action on action.step_id = step.id
join cmn_custom_scripts script on script.id = action.script_id
/* where ... add your filters here to find what you're after */
