BW Datasource error when connecting to sql server 2012

Hi,

I don't know whether it's the correct forum because my problem is between sql server and bw.

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 enter in the data source and say what sql server tables I can select for the datasource.

Can anybody help me?

Thanks a lot.

Regards.
