Hyperion Planning Hybrid Aggregation Performance Issue with Forms

HI Gurus,

We have created a Planning Applicaiton where we are getting performance issues in opening Forms. When we open the form at base level the form opens not great but aceptable time of 10 secs but as soon as we change the entity to parent level the forms takes minutes to open.

Just to add, we have Hybrid Aggregation is enabled on the Cubes and I am not sure if this will impact the performance.

Even with Suppress missing on it still takes less time but I cannot do this as the user need to enter details on the missing lines.
