2 entieties instead of one during creation odata from simple FM

Hello,

I have simple FM:

- importing 1 parameter 'praram'

- exporting 1 table 'table'

at my instance NW 7.4 during creation odata service in segw from this FM effect is

     creation 'table' enity and automatic 'tableSet' enity

at NW 7.0 in the same situation effect is:

eninty : 'table'

entity: 'param'

Any suggestion ?

Thanks !
