Hello. 

I try to develop a module, that changes the translation of the purchase app button to send an RFQ. Unfortunately the below mentioned code in the po file located in the i18n folder of my module does not work. I see, that all my other - module related in the same PO file translations work

My hypothesis is, that the purchase module overwrites my translation. 

My question is: How can a module overwrite a translation in standard ODOO modules.

Can you please help me out?

#. module: purchase

#: model_terms:ir.ui.view,arch_db:purchase.purchase_order_form
