Hi Maksim,

I've already seen this page.

I wanted to know more precisely the different aspect of this function.

For the moment my principal question is how to link different data tables?

Hi Adrien,

The answer for your question - there is no way to define foreign relations between tables using Java Dictionary.

Hi Maksim,

Thank you for your quick answers!

Do you know how to define foreign relations between tables in SAP NW?

Best Regards,

Adrien

Hi Adrien,

From database perspective - I don`t know such possibility. From object-relational persistence perspective there are 2 options - JDO and CMP EJB.

Check http://help.sap.com/saphelp_nw04/helpdata/en/d0/8785ac972e45479d397d1a19cf1080/frameset.htm

Hi Adrien,

You have two options:

1. Use entity beans to access data from Java dictionary and in entity beans you can define relationships between these tables.

2. You first deploy java tables on the server then run the foreign key contraints script on the database explicitly.
