External ID not found in the system: "report.external_layout_header" - odoo

Question

I want to migrate a module report from odoo 10 to odoo 11 but it seems that odoo 11 doesn't contain a module in addons called report. Can you help me and tell me with what I can replace it.

Answer 1

In Odoo11 the "report" module is integrated with "web" module.
Replace this report.external_layout_header with web.external_layout and don't forget to add 'web' in your dependency
inherit_id="web.external_layout"

Hello, omas
Can you Please write the following code:
<data inherit_id="web.external_layout_background">
<xpath expr="//div[hasclass('o_background_header')]" position="replace">
<div class="header">
<div class="row zero_min_height">
<div class="col-xs-12">
<div style="border-bottom: 1px solid black;"/>
</div>
</div>
<div class="row">
<div class="col-xs-6" name="company_address">
<span t-field="company.partner_id" t-field-options="{"widget": "contact", "fields": ["address", "name"], "no_marker": true}" style="border-bottom: 1px solid black; display:inline-block;"/>
</div>
<div class="col-xs-6 text-right">
<img t-if="company.logo" t-att-src="'data:image/png;base64,%s' % company.logo" style="max-height: 45px;"/>
