Asset planned values computed positive value Issue

Question

HI experts,
I have an existing asset problem where the planned depreciation values becomes positive. Why does it becomes positive? How does system calculates this planned values? We just did some adjustment to the Asset by Credit Memo and another Mark-up transaction. Sample:
Asset 1610600065
Planned Values - Transactions:
26.02.2011     160,000.00-     160     Credit memo in following year     64,000.00     0.00     0.00     SGD
26.12.2010     98,666.66     700     Write-up ordinary and spec     43,851.85-     98,666.66     98,666.66     SGD
26.12.2010     98,666.66-     700     Write-up ordinary and spec     43,851.85     98,666.66-     98,666.66-     SGD
26.12.2010     93,333.33     700     Write-up ordinary and spec     41,481.48-     93,333.33     93,333.33     SGD
26.12.2010     93,333.33-     700     Write-up ordinary and spec     41,481.48     93,333.33-     93,333.33-     SGD
26.02.2011     160,000.00     160     Credit memo in following year     64,000.00-     0.00     0.00     SGD
23.06.2011     160,000.00-     160     Credit memo in following year     60,000.00     0.00     0.00     SGD
26.12.2010     101,333.33     700     Write-up ordinary and spec     33,925.92-     101,333.33     101,333.33     SGD
                                                               26,074.08     101,333.33     101,333.33     SGD
But the planned/posted value for this period is positive:
Status Status Period Amount
Green Posted     1     6,666.67-
Green Posted     2     6,666.66-
Green Posted     3     6,666.67-
Green Posted     4     6,666.67-
Green Posted     5     6,666.66-
Green Posted     6     6,370.37
YellowPlanned     7     4,493.83-
Posted Values - Depreciation Posted/Planned:
APC transactions     400,000.00     160,000.00-     240,000.00     SGD
Acquisition value     400,000.00     160,000.00-     240,000.00     SGD
Ordinary deprec.     220,000.00-     26,962.96-     246,962.96-     SGD
Unplanned dep.                    SGD

I believe in your case, the tremendous reduction in APC cost has caused a tremendous change in planned depreciation.  System looks at the NBV and the remaining periods of useful life each time it calcs depreciation.  Of course also looks at depreciation key, Period Control, and OAYR Smoothing button.  Asset class can also be set for group depreciation.
If a credit memo reduced the APC value dramatically, then the amount of depreciation on the asset at that moment is more than enough so far.  This means that the next running of the AFAB program will reduce its amount of depreciation from the amount it was planning to book since it already has an excess of accumulated depreciation.
Please check in OAYR to know if your Smoothing indicator has been checked for the Company Code.  As I understand the system, if this indicator is checked - the system will not catch-up the whole difference in the next running of AFAB.  Instead, it will smooth out the adjustments due to credit memos, unplanned depreciation, and changes in remaining useful life over the remaining life of the asset.  When smoothing is set, one gets less drastic period to period change.
This setting should be in line with your accounting rules, such as in US GAAP changes in depreciable life are considered estimate changes requiring only prospective corrections, and so should smooth out impact over remaining periods of useful life versus immediate catch-up.
You may want to run a AFAR (check for recalc flags) and then a Repeat AFAB in the current period after making master data changes for depreciation.  All open periods would be impacted by master data changes if you run AFAB.
