Initiate and Fill BIA Index Step Fails in Process Chain

HI!

       In our weekend scenario for a cube, we refresh the data in a cube. What we do is, we delete BIA indexes before the data refresh in the cube, load the data, recreate the indexes using "Initialize and Fill BIA" step.

Last run the filling process failed and in the log it showed this message:

Lock for table 'table name'. Job will be restarted again later

We have it for many tables and at the end of the log:

FILLING_FAILED  >CHECK LOG!!!!!

Please any advice in this?

Thanks,

Ghassan Matar
