Alter label for dot-walking in extended table

[Jean Ferreira]

For the list view, for tables Service Offering and Technical Services, I changed the list layout in order to add these columns:
spm_taxonomy_node, parent and parent.spm_taxonomy_node

In my business case, we want to rename the label of the column spm_taxonomy_node to MY CUSTOM LABEL.

So, in my list view we will see
Name, My custom label, Parent, My custom label.

In order to to that, I went to the column dictionary and altered the Taxonomy node label to My custom label.

The parent column references a record of the same class.

This change worked for the taxonomy node column, but it did not work for the parent.taxonomy node column. 

 

I tried to create a onLoad Client script and it also did not work. 

It works if I change for all the CMDB hierarchy starting from cmdb_ci_service, but I need a solution only for the 2 mentioned classes.

Most likely the "Parent" field is a reference to "cmdb_ci_service" table, not one of the mentioned child classes.

This also explains why it works if you change it for this table, but not for the child tables.

In the parent column, I changed the label for the tables I wanted. 

I expected that the system to follow it.
