Sys ID of Task Table - Extensible or not

[NishaB]

I am creating an application on App Engine Studio. One of the tables for it is extending the task table. But I'm not able to rename the sys id of task table and use it? Is it possible to rename the sys id and then use it?

Hello @NishaB ,

Sys_id is the unique id generated for each record in ServiceNow.

You should never change sys_id and it is not recommended.And also You will not be able to changed it also in istance.

Thanks,

Hello @NishaB 

You cannot change the column name but you can change the column label....

Why to rename the sys id.., it is a system field which is unique identifier for each record.

Please make sure you are only changing in the extended table...

If you change the base table display name, it could effect the child tables. . 

Please mark the answer as helpful and correct if helped. 

Kind Regards,
