HFM dataunit

Hi Experts,

I am using dataunit for the first time as below.

set DU = HS.OpenDataUnit("A#P140101.E{E99999.[Base]}.V#<Entity Curr Total>.C1#TOPC1.C2#TOPC2.C3#TOPC3.C4#TOPC4.I#[ICP Top]")

As per admin guide, they mentioned only to use Account, ICP and custom dimensions. However, when i use Entity/Value dimension still it works.

So, my question is, if i use setdatawithpov, to which entity will it be written?

My requirement is to get the list of entities which has data against two accounts.

Thanks,

Meenakshi
