SAGE CRM - Sage 100 Integrating Orders

Dear Sirs,

I have a question concering the integration of sage crm with sage 100 trading.

when the integration is running successfully i have the option in the quote screen to click on "link to erp" in order to update the erp with the quotation.

However in the Order screen i can see next to the order the "not linked" and i do not have the option to click on "link to erp" is that a customization that we should do to link the order to the erp? or how can i integrate the order into sage trading?
