Issue with F-92 incorrect accumluated deprecaition calculated in the sale

Question

We have discovered that SAP processes the disposal in a correct way but very strange.
We found that although it does not do what appears to be a correct entry for accumulated depreciation at the time of the disposal (f-92) it proceeds to do a follow up correction in the following  monthsu2019 depreciation run to  make up the u2018shortfallu2019 on the accumulated depreciation.
I can best demonstrate this by an example of a sale that was made in recently.
Below is the retirement journal for the disposal (F-92) of asset 140769 in co 5000
"F-92"      Sale of asset 140769     "Posting Date 20.05.2010 (period 11"
"PK"     "Account"                            "DR"                  "CR"
1     Customer                            8000     
50     Sale of Fixed Assets                           7272.73

70     Asset 140769                    4425     
40     Clearing sale of FA     7272.73     
40     Gain / s on Sale FA     102.27
     "Asset 140769     year 2010"     
     Acquisition Value     11800     
     Ord Dep start of Year     4327     
     Planned dep (for year)     983     
     "Posted Depreciation"          
     Period 1     98     
     Period 2     99     
     Period 3     98     
     Period 4     98     
     Period 5     99     
     Period 6     98     
     Period 7     98     
     Period 8     99     
     Period 9     98     
     Period 10     98     
Notice the entry for the accumulated depreciation is for only $4425.00
The asset master values  although shows that it had $5310 accumulated depreciation charged to it to the end of period 10
Now the surprise u2026 for some reason SAP plans another depreciation entry in the following month of the sale.
In this case it the negative depreciation of 885 (9/10 of the depreciation) that it proposes for period 11.
The entry there would be
Dr Accumu2019d  Depreciation  885
                            CR Depreciation 885
When depreciation is run for period 11  it will be the final closing entry against the asset to finalise its balances are closed off to zero
This appears to be a very strange way of accounting for the sale
Your assistance would be greatly appreciated.

Answer 1

How the depreciaton calculation is calculated is based on the period controle rule in the depreciation keyfor asset retirement/sales  from the asset. It is based to on the value date you fill in the posting
