SAP BEx Customer Exit

Question

Hi Gurus,
I've implemented the code below for my report to display Required Start Date (MM/DD/YYYY) by searching and processing either a single Fiscal Year/Period (PPP/YYYY to PPP/YYYY) input or a range/interval Fiscal Year/Period (PPP/YYY) input. The details are,
1) Created 1 User Entry Interval Mandatory Variable under Fiscal Year/Period InfoObject (Display) - ZFYP_IN
2) Created 1 Customer Exit Interval Mandatory Variable under Required Start Date InfoObject (Output) - ZRSD_CX

ENDIF.
However, after doing extensive testing I discovered that the code is only able to process 1 period at a time versus an interval of periods as required.
For example,
Input Fiscal Year/Period Interval - 001/2011 to 004/2011
Expected returned dates - 02/27/2010 to 07/02/2010 (4 periods)
Actual returned dates - 02/27/2010 to 04/02/2010 (only 1 period, the 1st period and not the balance 3 periods)
Only the first period is returned versus the periods entered. I'm not sure what is missing from the code to process the entered interval.
Appreciate any help provided.
Warm regards,
Eric

Hi,
After looking your code, I think the problem is at the below mentioend part.
WHEN 'ZRSD_CX'.
READ TABLE i_t_var_range WITH KEY VNAM = 'ZFYP_IN'
INTO LOC_VAR_RANGE.
IF SY-SUBRC = 0.
CLEAR L_S_RANGE.
**This 2 call functions are used to convert the Fiscal Year/Period range into**
**Calendar Day range for use on further lookup in Required Start Date**
ZYEAR = LOC_VAR_RANGE-LOW(4).
ZMM = LOC_VAR_RANGE-LOW+4(3).
Here, you should put validation like this.
If not LOC_VAR_RANGE-LOW is initial.
      If not LOC_VAR_RANGE-HIGH is initial
          ZYEAR = LOC_VAR_RANGE-HIGH(4).
          ZMM = LOC_VAR_RANGE-HIGH+4(3).
         else.
          ZYEAR = LOC_VAR_RANGE-LOW(4).
          ZMM = LOC_VAR_RANGE-LOW+4(3).
endif.*
else.
put a validation to see that some input is given for fiscal year
endif.
only after these lines go for your function modules. This way, if your variable has range given, it would calculate till the higher range given for fiscal period.
