Architecture View

HI Experts:

Here I am facing some problem with configuring architecture View in SPRO settings:

I ' ve created Locality by copying the Standard Locality and renamed it and below that I have created Building ,Land,Room by copying standard only .

After that I have given the Screen Sequence and High Level Hierarchy also and saved It.

While Creating Locality in Easy Access I am getting below mentioned error.

*"BDT application REAO Supports only sub screen mode"*

and

some times "Number ranges not specified"

Pls guide me ..

Madan.
