The question:
I visited many sites for find solution of this issue.
But after creating system.xml
and acl.xml
Magento give me a report generated error.
Error
a:4:{i:0;s:140:”Notice: Undefined index: id in
/usr/local/ampps/www/mgn2/vendor/magento/module-config/Model/Config/Structure/Element/Iterator.php
on line 59″;i:1;s:6391:”#0
/usr/local/ampps/www/mgn2/vendor/magento/module-config/Model/Config/Structure/Element/Iterator.php(59):
MagentoFrameworkAppErrorHandler->handler(8, ‘Undefined index…’,
‘/usr/local/ampp…’, 59, Array)
Can you clarify this issues?

The Solutions:
Below are the methods you can try. The first solution is probably the best. Try others if the first one doesn’t work. Senior developers aren’t just copying/pasting – they read the methods carefully & apply them wisely to each case.
Method 1
In your system.xml
replace this
<tab>HelloWorldMVVM</tab>
with this
<tab>Pulsestorm</tab>
