Answer 1

User Exits For Billing
o USEREXIT_NUMBER_RANGE (Module pool SAPLV60A, program RV60AFZZ)
The internal number range used in the standard system is specified
in the billing type table and can be changed in this user exit. This
user exit is only called when the billing documents is created.
o USEREXIT_ACCOUNT_PREP_KOMKCV (Module pool SAPLV60A, program
RV60AFZZ)
In this user exit additional fields for account determination that
are not provided in the standard system are copied into
communication structure KOMKCV (header fields).
o USEREXIT_ACCOUNT_PREP_KOMPCV (Module pool SAPLV60A)
In this user exit additional fields for account determination that
are not provided in the standard system are copied into
communication structure KOMPCV (item fields).
o USEREXIT_NUMBER_RANGE_INV_DATE (Module pool SAPLV60A, program
RV60AFZC)
Depending on the number range, table TVFKD is used to set the
billing date (country-specific requirments in Italy).
USEREXIT_NUMBER_RANGE is automatically deactivated when this user
exit is being applied.
o USEREXIT_FILL_VBRK_VBRP (Module pool SAPLV60A, program RV60AFZC)
This user exit is only called when the billing document is created.
It is used to provide the header and the item of the new billing
document with deviating or additional data.
