I use these 2 pages to try to add or update my custom fields :
In my template and csv field, i have this :
product_sku custom_title custom_value custom_override custom_delete
P000023 onglets some value 1 1
P000023 Disponibilité some value 1 1
P000023 prixbase some value 1 1
P000097 onglets some value 1 1
P000097 Disponibilité some value 1 1
P000097 prixbase some value 1 1
P000117 onglets some value 1 1
P000117 Disponibilité some value 1 1
P000117 prixbase some value 1 1
I have added "custom_delete" as without it, it was not working better.
In this file : for the custom field "onglets" (editor field), i always have a duplication and not a replacement !
How to have a proper replacement when i import the file ? I would like to have : if the custom field does not exist, import the value, if the custom field have already a value, replace it with the new value...
