Travel Management does not support Delta option?

Hi all

I´m using SAP EHP for Netweaver 7.0

The problem is that I have transformations form 7.0, DTP and updates rules form 3x version in the structure of the cube

According to the SAP documentation, the data source 0FI_TV_01 does not support Delta update.

I would like to know if there is a way to overcome this no-delta allowed option in Travel management.
