Problem to connect to sql server 2012 from data source

Hi,

from BW I've created a db link using dbco transaction and, using ADBC_TEST_CONNECTION program the db linkg seems to be correct. Later, I've created a sql server source system using that db link and when I verify the source system I get some errors:

Message                                                    ID     Number 

EDI: there aren't interlocutor agreements      E0     332

Haven't been found enters in the enter table  E0    440

The base type ZSAM037 doesn't                 EA     447

However I can go into the data source and say what sql server tables I want to select for the datasource.

But when loading data to psa nothing is loaded.

Can anybody help me?

Thanks a lot.

Regards.
