Determination of Depreciation start date in Asset accounting

In this document, I will try to show by example how these different date fields are dependent on each other and how system calculates these value fields.

The master data of an asset (first tab) is shown below:


Based on the screen layout and tab layout configurations the above screen may differ.

The “Capitalized On” field is ready for input. User will have two options either to fill it with particular date or leave it blank.

Let’s consider:

Case 1: User manually entered the “Capitalized On” date

The field “Acquisition on” is read-only. Once the asset is capitalized , system will fill this value with “Capitalized on” field value.

Now, the capitalized date is manually entered and asset is created.


The asset is still not capitalized.

The field ODepr.Start  date field is still blank.


Now using external acquisition with vendor F-90 the asset is capitalized.


After Capitalization,


System copied the “Capitalized on” date to “First acquisition on” date field.

The ODep.Start date is based on asset value date and period control method in the Dkey.


Note that , there are two Depreciation keys used – LINI and MX04.

For LINI – system calculated ODep Start date as 01.02.2015 and for MX04 its 01.03.2015. (This is due to period control method in DepKey settings , although the asset value date is same.)

In Asset values explorer: Asset value date is as below (same as manually entered “Capitalized on” date value)


System settings of Period Control for Depreciation Keys:


Below is the system settings for Period Control keys for Acquisition transaction:


The above illustration explains the system behavior in calculating asset value date, depreciation start date and First acquisition on date values.

Case 2: The field “Capitalized On” field is left blank during asset creation


Now using external asset acquisition transaction (F-90) the asset is capitalized:


Note the document date and posting date.

Now the system refers the earliest of document date and posting date as Capitalized on , First acquisition on date.

Note: if posting date and document date are in different fiscal year, then posting date will be considered.


Asset value date is,


As described above, the depreciation start date is based on asset value date and period control method in Depreciation key(assigned to depreciation area).


system calculated the ODep Start date as mentioned above.

If in the depreciation key settings, “Depreciation to the day” check box is checked, then system ignores the ODepStart date and considers asset value date for depreciation calculation.


For further information on the Asset dates , please refer to below link:

Below is the reproduced information from above post:


system will automatically determine the value date in below scenarios (Not manually entered)


Any feedback/suggestions for improvements are most welcome.

      Nice Document .


      Please suggest on below issue if any idea -

      We have a case on Fixed Asset where Depre Key is LINK with following combination;

      Base method       0011   Ordinary: percentage from useful life

      Decl.-bal. method 001    0.00x / 0.0000% / 0.0000%

      Prd cont          012    01/01/01/01

      Multilev.meth.    001     0.0000%


      We have Fiscal year from Apr XXXX to Mar XXXX

      On Asset, Capitaliztion date has been maintained as 03/31/2019.


      Posting via MIRO on asset has been taken on date 09/30/2019...but ordinery Dep start date has been automatically set to 03/Mar/2020...which should have been 03/Mar/2019.

      We tested few cases with other assets where all posting are fine and dates set as per configurations expected above one asset.

      Thanks in Advance .

      Hi Ravish,

      Nice to ave your document.

      Just an update, system will not ignore Ordinary depreciation start date even if in the depreciation key settings, “Depreciation to the day” check box is checked.

      Depreciation calculation will always start from Ordinary depreciation start Date.

      Hi Nitin,


      Thanks for reading my blog.

      Regarding the observation on “Depreciation to the Day” check box functionality, System will ignore the Ordinary depreciation start date which is dependent on period control method in addition to asset value date. That means by ignoring period control method system considers asset value date as start date for depreciation as stated in this blog. Pls. refer to SAP help for this check box.


      Cheers !

      Hi Ravish,

      Thank you for your article, it is very helpful. I have an issue with my client in France. Depreciation to the day fonctionnality is active. In the "Posted tab", depreciation calculated per period are not the same due the number of days per month.

      My client want depreciation calculated per period have the same amount.

      Do you know how I can solve this ?

      Thank you in advance.
