I added a column in relationship tab, to do that I edited the civicrm/CRM/Contact/BAO/Relationship.php
I already added columns with fields existing in the base of civicrm but now I'm trying to add a custom field of a custom group as a column.
In the function makeURLClause() I don't know what to add in the select so it can select my custom field.
the name of the custom group is civicrm_value_r_le_11
the name of the custom value is fonction_dans_l_entreprise_83
civicrm_civicrm_value_r_le_11.custom_83 as custom_83, but it didn't work
