Custom Table when pulled as a related list, 'Edit' button on the RL does not give all records

Salma Laskar · ‎05-29-2025

Hi,

A custom table say 'u_test_table' created with only two reference field 'Task' referencing to task table and 'CTR' field referencing to test result table.

when this custom table is pulled on the test result table as a related list, as an admin when 'Edit' button is clicked, it does not give all the tasks under collection slush bucket. The bucket on left side from which we want to pull tasks on the bucket on right side in 'sys_m2m_template' form.

However, if we open the custom table from the navigation and try entering new data in the table, we can select all tasks on the reference field 'Task' on the custom table.

Please let know if you can identify the reason for it.

Thanks!

Hello Folks,

Thank you for all your responses. Appreciate it sincerely!

I did raise a hi case with servicenow support and got this resolved. Here is what was needed -

Create a custom UI action say "Edit..." with below configurations (this is specific to my use case).

Table : sn_vulc_m2m_test_result_task {this is the custom m2m table that I've created}

Action name : sysverb_edit_o2m {you might want to keep it exactly this}

Active : True

Show insert : True

Show update : True

List banner button : True

Condition : (new GlideRecord(current.getTableName())).canWrite() && RP.isRelatedList() && !RP.getListControl().isOmitEditButton()

Script :

var uri = action.getGlideURI();

var path = uri.getFileFromPath();

uri.set('sysparm_m2m_ref', current.getTableName());

uri.set('sysparm_stack', 'no');

uri.set('sysparm_query', '');

uri.set('sysparm_collection_related_field', 'u_task'); //{'u_task' this is the custom field on the custom m2m table referencing to [task] table}

uri.set('sysparm_collection_related_file', 'task'); // {Task table - all of the records from this table are to be displayed on the left slush bucket under collection}

action.setRedirectURL(uri.toString('sys_m2m_template.do'));

I tried the same steps and when clicked Edit button it doesn't show me any records

Strange.

Did you try creating something similar for other tables in global scope?

If my response helped please mark it correct and close the thread so that it benefits future readers.

Hi Ankur,

Tried in PDI for OOB tables by creating an m2m table.

user name :edit.ui

pwd : pWd&111pWd&111

you can check in this link. It gives the same result. Can you identify why ?
