Error assigning update type to flow type 1100, sign -, contract type 6

Dear Experts,

I get the following error when i try to create a cross-currency swap instrument in TO01 for transaction type 302- Basis'

"Error assigning update type to flow type 1100, sign -, contract type 6"

I have checked the assignment of flow type to update type and they are fine. I have assigned flow type 1100 with update type 'DE1100-' with direction '-' for product type 62B and transaction type 302.

Is anything wrong with the configuration?

Thanks,

Vinod
