Error in Depreciation Proposal - Wrong requirements for account 1732. Please check code part demands.

Please check your posting control setup and asset preposting - usually depreciation uses code part value like cost center from object preposting - if no cost center indicated on object, this error is noticed.
I would check new objects (depreciated for the first time this month) in first instance

Please go to account and query for 1732 -- on the code part demands tab -- see how the demands are setup (like asset is probably set to  mandatory).

Then go to your posting controls and confirm that the posting controls are setup to post the same code parts listed on the demands of the account.  (check FAP5 and FAP6)
