Sage 300 2018 - BX module


A customer that has an old Sage 300 2018 (v65) installation, its getting an issue and apparently iyt is related to BK Services but when check its modules installed in System Ingo I saw BX it is active with an old v62A version not 65A. But not sure what BX means? They have only finatial modules : GL, AR, AP, Multicurrency and Optional Fields. AS, CS, BK, GP as usual but not sure what BX means!!!

Any idea?

Thank you very much
