Generic datasource

Hi,

While creating Generic datasource for MM component, the following message is displayed,

'Field EISBE with reference field MEINS: Reference table MARA is replaced by ZOXDVS0026' and it is not allowing to save.

In the transparent(customized) table, this field has reference to the MARA table for a few key figures (like EISBE).

Cant we create the generic datasource for this scenario?

Please guide me the right solution as soon as possible.

Thanks a lot in advance.
