User able to enter interbranch sales order even though interbranch flag is off in processing options

Hi All,

We are using JDE 9.1

There is a case where user is able to commit inventory from a B/P of a different company in order detail other than the header company.

I checked the P4210 processing options but interbranch flag is turned off and there are no order types mapped.

Please suggest any additional setups that could be driving this as per standard JDE and how can this be prevented.
