About variant program in isu-billing

Question

Hi guys,
Is there any1 who know something about variant program in isu-billing?
My question is: how do the operand communicate with billing schema
interactively? I can't understand the types in the FM of an variant, can
someone explain that to me? or have some materials about it? pls send me.
Thx in advance, points will be rewarded no matter whether it is useful.

Answer 1

1.What is operand groups
An Operand group is used to group operands for display purpose in the rate, rate category and installation facts.
You allocate the operands to the operand groups while defining the operand in EA50.
Ex: You can allocate operands 'Ordered Demand' and 'Minimum Demand' to operand group 'Demand'
2.How to define a hierarchy of operand group?
You can assign three levels (Top level, First level and Second level) to the hierarchy of a operand group........
This can be done while defining the operand group itself in ....
SPRO-> SAP Utilities-> Contract Billing-> Billing Master Data->Rate structure-> Operands-> Define Operand Groups.
Ex: You have a upper level operand group ZOPRG and two lower level operand groups ZOPRG1 and ZOPRG2, enter ZOPRG as the upper level operand group for ZOPRG1 and ZOPRG1 as the upper level operand group for ZOPRG2.
Hence ZOPRG will assume top level and ZOPRG1 and ZOPRG2 will assume first level and second level respectively.
3.What is Weighting procedure ,Linear weighting ?
Liner weighting is the fixed linear portion that is added to the other weighting procedure during the determination of the
expected meter reading. You enter the fixed value in the register data during installation or in the rate of the installation structure along with the validity period.
Hope this will suffice!
