ASKB - Purpose

Question

Hi
Though I have myself handled it in the past, I could not recollect due to huge time gap.... I also browsed through various posts of the forum, but could not recollect my understanding yet...
1. (Is this understanding correct??) As far as I remember, ASKB is used to post depreciation for Non-Book Depreciation areas into the Parallel Ledger... i.e. if the posting indicator in OADB is 2 OR 3
2     Area Posts APC and Depreciation on Periodic Basis
3     Area Posts Depreciation Only
2. Another purpose of ASKB., which I remember very clearly is that at the time of Asset Sale, the Profit/Loss on the transaction is calculated as per Dep Area 01 and posted in all other dep areas...
Later on, when ASKB is run, it calculates the Delta values and posts in the parallel dep area and parallel ledger.... However, I could not recollect whether dep is also posted during ASKB or not
3. Posting indicator 2 in OADB is used if APC Values are different for Leading / Non Leading Ledger..
My question is how can an APC value be different for 2 dep areas if I am purchasing an asset for say, 1000 USD.... Assume Indian GAAP is my Book Dep Area 01 and US GAAP is my Dep Area 02....
Is it because of the fact that some expenses like (eg: Freight 50 USD) might be capitalized for Dep Area 02, but not for Area 01????
In that case, how is the differential APC posting 50 USD is made to the Dep Area 02 / parallel ledger from ASKB?? As far as I know, ASKB does not offer any option to enter the 50 USD amount manually for an asset... Is this done from ABSO???

In order to use the ASKBN transaction, you have activate the SAP R3 Enterprise Extension. 
First option in the IMG menu.
Requirements: See SAP Note 588364.
This allows you to post directly to the ledger without without having to generate a batch-input session. 
In addition, you can post directly online to the general ledger from the dialog posting transaction from depreciation areas other than the master depreciation area 01. Or you can update the values from a depreciation area to a special ledger using a different accounting principle.
This transaction is much, much better to use than the ASKB. Plus it works similar to your deprecaition posting. The only complaint that I have is that you get a "log" in test mode, but it does not create an actual posting log when executed like the depreciation postings creates. 
In order to use this transaction, you must configure the depreciation area where you are capturing the non-US GAAP asset requirements to post to the ledger in addition to the Area 01 that will automatically post. 
You will also have to establish an external document type, document number range and a reverse document type (OBA7) with account types allowed for Assets and G/L Accounts. 
The document type needs to be different from the document type used for the standard depreciation posting (AF) and AA postings (AA). We used AZ. We are also using a number range outside of our standard AA and depreciation document numbers.
