CTM-Aggregated Planning for AFS scenario

Hi All,

Below is the scenario

I have one header (FG1) and many sublevel(FG1B,FG1L,FG1K) .The scenario I am talking is related to AFS.

I can see my hierarchy correctly in transaction- Maintain hierarchy for  location product.

In CTM Under aggregation I used below setting.

Planning Level: Header Level

Hierarchies

Location Product:assigned above hierarchiy.

I created demand for sublevel FG1B,FG1L and FG1K.

When I use demand simulation it is not showing any demand at header level.Expectation is it should aggregate demand from lower level to header level and plan accordingly.

I am not able to understand what I am missing.

Need help in resolving this.

Regards
