Problem loading from ODS to ODS

Hi all,

i got 3 ODSs: ODS A, ODS B and ODS C. I'm loading data from ODS A to ODS B and in the actualization rules i'm reading data from ODS C to fill a field of B.

The problem is that when i export the data from A to B the load stays always in yellow, the monitor says that the process is finnished, on SM50 no activity is detected, and no record is inserted on B.

When i comment the code where i read from ODS C, the load works perfect.

How can i solve this.

thanks a lot
