First you need to understand the difference between ODQMON and RSA7.
RSA7 - Is for maintaining the Delta queue for BW system.
ODQMON - Is for maintaining the Delta Queue for external systems(BODS)
So just you need to activate from RSA5 and activate R\then replicate in bw side.
Then do all the needful activity in BW side.
And Delta Queue will maintained in RSA7.
