Total Business Volume RBVT getting summed at header level in contrast to REBV

[anna_ha]

Hello Colleagues,

we would like to use scales across mutliple clients in Multi-Customer condition contract type with the help of RBVT condition that SAP advises to add and a new scale base formula that refers to RBVT as scale basis of RES1.

Now the pricing at tem level of a settlement document looks correct:

However, at header level total business volume is resulted as the sum of item values:

We expect it to behave, similar as REBV at header level:

The wrong value  of RBVT at header level leads to wrong %-Scale determination.

So the RES1 gets overwritten at header level after the correct calculation in the first place and re-distributed at item level.

Any ideas what is misisng here? Or some pricing procedure has to be maintained for RBVT to corrcet such behaviour?

P.S. we observe the same behaviour in both S/4HANA and ERP Systems.
