Sample of plan version customer exit code

Question

Hi! We have a requirement for Forecast accuracy report to be able to report comparison of current actual v current month forecast and
forecast 1 month ago, forecast 2 months 2 up to 12 months ago. I'm using Calculated/Restricted Key figures with variables "0FISCYEAR & and 0P_FYEAR" with offset and plan version variable 0VERSION & OP_VERS3 but not restricted. The offset for period/year works but not sure how to link it to a plan version specific to period/year. We don't want the variable for plan version to be fixed. We would like to pull the values of the Cal./Rest key figures for period/year and specific version. In our case, we use versions 1, 2, 3 up to 12 for 2010, and version 1 represents 01/2010 forecast/plan version, version 2 is 02/2010 up to 12/2010 version 12. And for 2011, we use versions 101, 102, 103 up to 112. 101 is version specific for 01/2011, 102 for 02/2011 up to 112 for 12/2011.  Same thing for FY 2012, our versions are 201 (representing version for 02/2012) , 202, 203 up to 212.  We have the same pattern of versions for 2020 as well (starts from 01 to 12; 101 to 112; 201 to 212 up to 901 to 912).
We would like to be able display the values for 12 rolling months for the version specific to period and year as mentioned above.
Example - in the query, I enter period/ year "03/2011" and version 103 (which represents the version for 03/2011). The result of the query should show up the following CKF/RKF columns:
1. Current Actual 03/2011
2. Current Forecast 03/2011 version 103
3. Forecast 1 month ago 02/2011 version 102
4. Forecast 2 months ago 01/2011 version 101
5. Forecast 3 months ago 12/2010 version 12
6. Forecast 4 months ago 11/2010 version 11
7. Forecast 5 months ago 10/2010 version 10
8. Forecast 6 months ago 09/2010 version 09 up to forecast 12 months ago version 03.
I think we will need a short coding/customer exit for variable version but donu2019t know what needs to be done if using enhancement.  I created a variable customer exit for plan version "ZVAR_MULTIVERSION_EXIT".  Type of variable is characteristic value, processing type is customer exit, reference characteristic is "0VERSION", other basic settings - multiple values and optional.  Please advise if anything I need to change on the settings for plan version variable.  Then my next question is how to code this scenario or maybe you can provide a sample abap code and how to link the customer exit to the "ZVAR_MULTIVERSION_EXIT" plan version variable.   Please advise and greatly appreciate any help and input you can provide.
Thanks a lot in advance for your help.

Hi,
Write the code as follows, it will solve your requirement:
"Declare work area WA_RANGE with type same as I_T_VAR_RANGE.
when 'variable_name'.
     IF i_step = 1.
          REFRESH e_t_range.
          data: v_date type sy-datum.
          data: v_mon type I length 2.
          data: v_year type I length 4.
          data: v_month type /bi0/oicalmonth.
          v_date = sy-datum.
          v_mon = v_date+4(2).
          v_year = v_date+0(4).
          v_year = v_year - 1. "Previous Year
          concatenate v_year v_mon into v_month.
          WA_RANGE-SIGN = 'I'.
          WA_RANGE-OPT = 'EQ'.
          WA_RANGE-LOW = v_month.
          append wa_range to e_t_range.
     ENDIF.
Hope this helps.
Regards,
Joe
