Hi, 

I want to insert the customer number in the information block in document Layout DIN5008 for invoice, sale order etc. reports . 

When i insert the link to customer numbe in information block under invoice number, etc.  in QWeb file account.report_invoice_document  nothing happends.  Also when i delete some information for example invoice date, delivery date, etc. nothing changes.

But when i insert this in the invoice body for example under artikel discription the customer number will be shown.

In which file do i have to make the changes for this?

Many thanks for help!
