TO Splitting in WM

Hi SAPgurus,

I am facing a problem in WM. TO's in our warehouse are splitting for a single storage type i.e separate TO is created for only that storage type every time we have stock placement in the warehouse. All other storage types are considered in single TO.

We have not configured TO splitting in the warehouse but still it is happening and that also only for single Storage type. Can anyone please throw some light on why it is happening? I would really appreciate help.
