customer import showing wrong BU

Hi All,

we have loaded 2 customer records one bill to & ship with expected/correct BU but after load can see it is showing wrong BU, any specific reason, how system will take other BU, even FBDI file & uploaded zip file showing the correct BU?

can anyone update if similar issue you have observed & what was the root causes & how we can update with correct BU. we have reloaded the same data using both simple & Bulk FBDI with correct BU but its getting no change & also no error.
