Hello Ravi,
thanks again for your help.
Our origin idea to use the SQL statement "IMPORT FROM" in a script in a loop does not work in fact. In the meantime we received the confirmation that "IMPORT FROM" is not supported in sql script and also not planned to enable this.
So it seems - as you have explained that BODS or any other ETL tool - is the only solution.
As last option we think about to use IMPORT functionality of catalog objects - with catalog and data. If we find an easy way to do this we update this post.
best regards,
Axel
