For my client system there are lot of depreciation keys defined. Some are standard while others are customized. As per their requirement only customized keys to be populated while creating asset by AS01 or AS02.
I want to make that keys such as LINA, LINB etc. should not get populated. I have checked on user side and its working fine, i want to test this from Configuration. Please tell me where I can see that only customized keys can be assigned to asset class in SAP.
