Orderable On the Web flag may be enabled only if Customer Orders Enabled is on''

Oracle EBS - R12.1.3

we are getting error as ''Orderable On the Web flag may be enabled only if Customer Orders Enabled is on''  while assigning an item to child org through API.

(we insert template having Customer order enabled flag as = N

and Orderable on web flag = N )

and in Master Org we have those values as Y and Y for both..

since the both attributes are org control.

but still we get this error. As item stuck in item interface table having values as

Customer order enabled flag as = N and Orderable on web flag = Y

we dont understand why the Orderable on web flag value turned in Y as we passed it ''N"'.
