Unicode migration and dead datasources.

Hi gurus.

I am facing an issue. We have changed BW700 to BW702 and did Unicode conversion. From this time I am not able to upload data from MS SQL connected via UD Connect.

First lookable difference is that all fields in Proposal tab of datasource is 2 character shorted from the start and fields Type, Length are empty.

When I try "Test Unicode" in sm59, I got Target is Unicode. But when I try Preview tab, I got no results.

When I change sm59 to NonUnicode, the Proposal is the same and when I try Preview, I got shortened values and in case of characters (texts) it is all like in chinese.

Sure it is impossible to upload the data. In first variant I got nothing, In second I got garbage that falls of unacceptable characters.

Codepage of the source is Win1250 (Czech).

Can you help me, please?

Thank you.
