Does not copy the field on background script

[Lion Kesler]

Hey
I'm trying to copy field Project to field service

(The second fields are reference)
When I run I see that the field changes but I don't see the value

the field

the script:

[Suyog Aptikar]

@Lion Kesler are both fields referring to same reference table, reference fields hold sys_id of the record.

can you please let me know what are you trying to achieve?

[Lion Kesler]

This is not the same table
But the names are the same

@Lion Kesler Do the fields Project and Service share a common reference table? I am asking this question as the sys_id of the project field should be available inside the reference table of service field then only the service field would be populated correctly, otherwise it won't.

Hope this helps.

Project and service istogether in incident table 

but deferent reference
