Direct and Flexible loading for Attributes for a Info-object?

Dear all,

Is it possible to have both Direct and Flexible update for Attributes of an Info-object from two different data sources from the same source system(R/3) . The reason being that the first data source can not be extended in R/3.

When this scenario is tried For Flexible loading The data loading is not successful in BW.No errors/dumps found.

Regards,

Amu
