GL Account - Cost Element category need to be maintained as "90"
Category 90 cost elements enable you to check the budget of an order or project when you acquire fixed assets that can be directly capitalized. To do this, enter the capital investment order or the WBS element in the corresponding field of the asset master data. Asset Management (AM) ensures that the specified order or WBS element is automatically entered in the document during the asset acquisition.
