While doing the same in Development I used T-codes OBAL &amp; OGAL to reset the data of Asset as it was not allowed by the system to make changes. Now when I have transferred the Transport Request to Quality system is showing error as "SYST: You cannot change the depreciation periods" Message No. AA662. This error is shown in old assets in which there was some balance along with accumulated depreciation. When I am viewing asset explorer through AW01N &amp; asset balances through AR01 it is showing error. For New Assets it is working fine. I would like to know whether there is any solution for the same.</P></BODY></HTML> Fri, 07 Sep 2012 11:40:47 GMT former_member835775 2012-09-07T11:40:47Z https://community.sap.com/t5/sap-for-high-tech-discussions/depreciation-key-changes/m-p/9003695#M18 <HTML><HEAD></HEAD><BODY><P>Hi,</P><P></P><P>We have configured depreciation keys according to monthly calculation of depreciation but after posting depreciation for 3-4 months through AFAB in Production system Client requires it to be changed to Daily Basis calculation of Depreciation.
