data services - function table structure not correct

Hello Everyone!

I am using Data Services to read a RFC from my BW system, which is defined as a "Source BW" datastore in DS.

After importing the function, i realize that the structure of the function is not imported correctly.

When i look at se37 in BW, i can see the correct structure of import table parameter:

and then looking at table E_T_GRID_DATA:

While in DS, E_T_GRID_DATA has only this "Line" component:

has anyone faced this and now how to import the correct structure ?

Thanks in advance,

Liron.
