I did some change in Migraton Object Routing (tcode LTMOM). My project was generated Runtime Object successfully. I run tcode LTMC and import file, execute step by step.
After that, I got error page "500 internal server error". Try again multiple times and I still saw that error.
My basis colleague check and found this dump: Database error text: "SQL message: single-row query returns more than one row".
Have you got any idea?
