Answer 1

I am attaching the code of the userexits:
***INCLUDE RV60AFZC.
This include is reserved for user modifications                      *
Forms for invoicing                                                  *
The name of modification modules should begin with 'ZZ'.             *
      USEREXIT_NUMBER_RANGE_INV_DATE                                 *
      USEREXIT_FILL_VBRK_VBRP                                        *
      FORM USEREXIT_NUMBER_RANGE_INV_DATE                           *
      This userexit can be used to determine the numberranges for   *
      the internal document number. This userexit can be used when  *
      the number_ranger should impact the invoice date via table    *
      TVFKD.                                                        *
      If this userexit is active the USEREXIT_NUMBER_RANGE is not   *
      processed anymore, that means this userexit has priority.     *
      US_RANGE_INTERN - internal number range                       *
      This form is called from form LV60AU02 and LV60AU11           *
FORM USEREXIT_NUMBER_RANGE_INV_DATE USING US_RANGE_INTERN.
Example: Number range from TVFK like in standard
US_RANGE_INTERN = TVFK-NUMKI.
ENDFORM.
      FORM USEREXIT_FILL_VBRK_VBRP                                  *
      This userexit can be used to fill fields in VBRK and VBRP     *
      Be aware, that at this time the work areas KUAGV KURGV        *
      KUWEV and KUREV are not filled.                               *
      This form is called from FORM VBRK_VBRP_FUELLEN.              *
FORM USEREXIT_FILL_VBRK_VBRP.
Example: change Tax country
VBRK-LANDTX = T001-LAND1.
*{   INSERT         MRDK900206                                        1
*if sy-tcode = 'VF01'.
read table xkomv with key kschl = 'ZTOD'.
if sy-subrc <> 0.
   clear xkomv.
   xkomv-kschl = 'ZTOD'.
   append xkomv.
endif.
*endif.
*----Commented
READ TABLE XKOMV WITH KEY KSCHL = 'ZTOD'.
IF SY-SUBRC <> 0.
   CLEAR XKOMV.
   XKOMV-KSCHL = 'ZTOD'.
   APPEND XKOMV.
ENDIF.
*----End of comment
*}   INSERT
ENDFORM.
*eject
