Syntax seems okay. Check whether the first view is getting created before the second one.

how can I check it? In the code, the block with Xpath is below the main block. Both blocks in one xml file

Comment out the second block by putting a <!-- before, and a --> after the block like so and upgrade your custom module to see if the the first view is getting created correctly.

<!--

<record model="ir.ui.view" id="creative_form_for_manager">

<field name="name">creative creative form for manager</field>

<field name="model">creative.creative</field>

<field name="inherit_id" ref="creative.creative_form"/>

<field name="groups_id" eval="[(4, ref('creative.group_creative_manager'))]"/>

<field name="arch" type="xml">

<xpath expr="//notebook" position="replace"></xpath>

</field>

</record>

-->

This doesn't work either =(

Please check is there any other view with same record Id

module_form

No. This only one. This code worked fine in odoo 10

Is it possible to upgrade the respective module without this code

Hello. check out my today comment. I misled you with my module name ((

yes. Without this code my custom module correctly loaded

could you try with changing attributes instead of replacing

<xpath expr="//sheet/notebook" position="attributes">

<attribute name="invisible">1</attribute>

</xpath>

Element '<xpath expr="//sheet/notebook">' cannot be located in parent view

No , error : "External ID not found in the system: base.module_form"

I have edited my earlier post and added a screenshot of base.module_form for your reference.

If it does not exist, it may indicate that the migration is not handling the views correctly.

Sorry ... check out my comment today ((
