During the fiscal year change in asset accounting (transaction AJRW), errors are encountered that prevent the asset values from being carried forward to current year.In the log of the fiscal year change a generic error AA707 is displayed indicating that there has been an error. The long text of this message suggests to check the asset values in the asset explorer (transaction AW01N) to have more information on the specific error.
However, when calling transaction AW01N no further information is displayed in the asset explorer (AW01N).
At this point, the user is blocked and do not know how to carry on and conclude a successful fiscal year change.
In order to be able to know which is the specific error, an easy debugging activity can be done that will provide the specific error. If you are not an ABAP expert, no worries, just follow simple below steps:
1.-With transaction SE38 set a break point in program LARF1U02 below CALL FUNCTION “RA_FISCAL_YEAR_CHANGE” as you can see.
2.- Run the fiscal year change
3.- The system will stop on the break point. Then, by double clicking on the text LT_ANFM  in the program code the internal error will be shown (LT_ANFM  – ID = “AA” LT_ANFM  – NR = “656”) and the relevant deprecation area (LT_ANFM  – V1 = “60”).
4.- Verify the text of the error in transaction SE91.
5.- Finally, if necessary, correct the customizing to avoid the error and execute the fiscal year change succesfully.
