Hi Manu,
please provide a screenshot of your movement type config.
Are you sure you have maintained the right movement type?
If you check dynamic bin, in case it doesn't take delivery number as
storage bin, it should take 0000000000 as a bin not WA-ZONE.
Please give us a few screenshots, movement type config, your stock
in 910 storage type after creating TO, your stock in 910 after confirming
TO. You can list your stock through LX02, or any other t-code like LS24...
