Cannot access Account [customer_account] table with App Engine - why?

[Peter13]

Good morning

I am in learning mode so please forgive me if the answer is either obvious or in the docs, I did not find it.

My question is: I am trying to build an App via App Engine Studio which is based on/extends the customer_account table:

But when I am searching for the table in the Engine Studio, it does not show:

What am I a doing wrong or did not understand?

Thanks

Hi

the reason is the unchecked value for "Extensible" at section "Controls":

So you can use that OOTB table, but there are good reasons why you cannot extend that table.

If you need additional fields, just add them to the table "customer_account".

Thanks @Maik Skoddow , that totally makes sense.

Let me ask you this then: (how) can I build an App which accesses data from the customer_account table directly? Or maybe I am using this wrong.

Background: I have added a few custom fields in the customer_account table and I want to create a wizard-like, several step guided process for a new customer to fill in these fields, validate them etc.

During my research I found the possibility of Wizards OOTB for Service Catalog only, not for the Service Portal (https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB06851) and Record Producers are not guided/good looking enough.

Could you point me into the right direction maybe how I could best implement this?

Thanks
Pete
