ORA-30926: unable to get a stable set of rows in the source tables

Hi,

I am doing a merge into statement across a database link and keep getting the ORA-30926 error: My merge into statement is below:
Any ideas - thanks for looking;

This error can come in the merge statement due to dupliate data in the tables. Can you verify whether there are any duplicates.

also have a look at this url

or instead of using "USING sku_invn@wmsp b", try with an inline view "USING (select ... from .. where ... ) " followed by ON (..)

just ensure that the inline view you are creating can pick up the data without duplicates after which your merge should be able to work fine. test it out.

Thanks
