User Exit: AFAR0002. How to change value in field: ANLC - NAFAP?

Question

Hi,
At the moment I am working on custom Depreciation Key for which the depreciation for period (and subperiods) will be recounted and taken into account for depreciation posting.
I try to use exit AFAR0002 for this purpose.
I am able to count and change the value of depreciation for each subperiods. The problem is, that I cannot change the value of "Ordinary depreciation that is planned for the asset in the current fiscal year" for the pierod '000'. Due to this, in the last period of the current fiscal year system tries to reverse the sum of planned depreciation in previous subperiods. It simply tries to meet the "planned depreciation for fiscal year' with the sum of planned depreciation for subperiods.
example:
ANLC-NAFAP = 100.
Active Asset value = 1000
Depreciation for periods:
001     ->     -50
002     ->     -50
003     ->     -50
004     ->     -50
005     ->     -50
006     ->     -50
007     ->     -50
008     ->     -50
009     ->     -50
010     ->     -50
011     ->     -50
*012     ->     450
planned value -> -100
The questions are:
1. is it possible to change value in ANLC-NAFAP in this exit
2. How it sould be done.
Thanks in advance for help.
Regards,
Wojciech

Answer 1

Dear Paul,
I had run AFAR. The report changed to '0' the value of ANLC-NAFAP  field - sth changed - thanks.
But I still have a problem to set this value to the sum of planned depreciation for each month. At the moment, in the last period the system tries to reverse all planned "sub"depreciation to '0' in total.
Is it any additional condition that has to be fulfilled in order to change the value of "Ordinary depreciation that is planned for the asset in the current fiscal year" for the pierod '000'?

Wojciech
