Hierarchy expand/collapse on 'Custom Extension' Web Item

Hello All,

I have a WAD issue, please help me to fix it.

There is a Web Item 'Custom Extension' which has an ABAP class to derive a hierarchy for an Infoobject based on DSO data. There is no hierarchy configured for that particular infoobject.

Now the display for that hierarchy is set upto level 3 but the customer wants the see only 2 levels displayed.

please let me know how can i get the hierarchy get collapsed.

P.S: When we click on the node, that value is passed to the affected dataproviders and data is restricted in it.

Thanks,

Dinesh
