Appending existing standard CDS view with CDC annotation

[arvshar2]

Hi Gurus,
What is the best practice to change existing standard CDS view (example I_Actualplanjournalentryitem) to CDC enable. I understand, we can create custom view on top of this CDS view, but wanted to validate if this is correct and only way.
Any clue would be helpful.

Hi @arvshar2, were you able to complete this on the I_Actualplanjournalentryitem ?

Hello @arvshar2 

I would try to avoid changing a SAP Standard View... it might cause trouble later in the next release upgrade.

I went through some of the underlying views, and in this one I_GLACCOUNTLINEITEMRAWDATA you can find a CDC annotation. So I would create my own view with a CDC annotation on top of the one you named ... similar to that CDC example, if you cannot use that view. To be honest I did not check what happens in between.

Thanks BR, Martin for quick reply. I tried to create custom CDS view on top of I_Actualplanjournalentryitem standard view but getting error: Namespace of DDL 'ZI_ACTUALPLANJOURNALENTRYITEM' does not match namespace of VIEWNAME 'IFIACTPLNJEICSQL'. I have not used any CDC annotation yet. Any clue.

Hello @arvshar2,
without seeing your actual coding I don't know what is wrong... maybe this page helps you?
