APO DP - loading from InfoCube to planning area

I am using APO DP V5.

I have the following situation:

1. I am extracting sales history data at the end of each day from a connected ECC system into an InfoCube, using delta logic, so in the Cube I just have the new sales history transactions (despatches) for the day

2. I am then loading data from the Cube to my DP planning area via transaction /SAPAPO/TSCUBE

I assume I must have the 'add data' flag set for each key figure in this transaction, to ensure I see the consolidated sales history in the planning area.

Is this the 'best practice' approach for regular loading of sales history? I assume it's better to have a 'delta' approach for the Cube, for improved performance.

Thanks, Bob Austin
