Persistent Classes and inheritance

[Former Member]

Hello everyone,

i have a persistent class zcl_p_konto which should act as a base class for persistent subclasses in further development.

In order to support polymorphic instantiation of persistent subclasses through zcl_p_konto's agent, zcl_p_konto's persistence mapping contains a type identificator which is of the type os_guid in the underlying table.

When trying to activate zcl_p_konto and its agents, i get the following error message:

Class ZCB_P_KONTO, Method IF_OS_CA_PERSISTENCY~GET_PERSISTENT_BY_KEY_TAB

The component "TABLE_LINE" is not contained in the table

"KEY_TAB_FOUND_LOCAL", or the key is not statically declared.

cheers,

Jens

As the problem is still unsolved:

We have a class zcl_p_account and a subclass zcl_p_savings_account. They both share the same range of account numbers.

What we need is a service, that retrieves the object with a specific account number, which is of type zcl_p_konto or zcl_p_savings_account, depending on the account type.

Any hints why we get those compiler errors? push

kind regards
