TRSF : DPPMCS02 -> DBFICS04 (Solvay) & TRSF: ODS_PMEN -> DBFICS02 (Rhodia)

Solvay / Rhodia :
The rule consists to split the costs on the PM orders according to the distribution rules on WBS Elements in table COBRB (Extracted to DSO DSSCOBRB (Solvay) and DSRCOBRB (Rhodia)):
We look for settlement type "Per" (by period) and, if there is no, we look for settlement type "GES" (cumulatively). The planned delivery date (scl_deldat) must be contained in the validity period of the distribution rules (COBRB-GABJA (Valid-from year) and COBRB-GBISP (Valid-to year)).
The CO original line is duplicated for each line in table COBRB where a WSB Element is filled applying the settlement percentage rate to the amount in a new ratio K_settlmt (the original amount (0amount) is conserved as it was in the first line of the split and is cleared in the other).

The rule consists to split the costs (and the quantities) that are posted on the PM orders according to the costs (and the quantities) that are transferred from the PM orders to the WBS Elements (We want to keep only the costs that are transferred to WBSE but to preserved the detailed on the primary costs that are lost at the time of settlement on WBSE):
We filter on the costs sent to the PM orders (PM order is the receiver = db_cr_ind "S").
These costs are split (in a new ratio K_settlmt) on each WBS Element for which costs are transferred from the PM order during the period.

Partner object mapping (R3):

Partner objects are mapped from a generic field "Partner IO val" (RSPAROBVAL) to specific infoobjects "Partner Costs center" (0PART_CCTR), "Partner WBSE" (C_PARTWBS), "Partner Order" (C_PARTORD),... according to the partner type (RSPOBART). It is done using the Function Module 'CO001_BIW_PARTNER_DECODE' as provided by the SAP Business Content.

Datasources customer exit:

• 0PM_OM_OPA_2: retrieve additional data from tables EKKO, EKPO, COEP and AUFM. The quantity "SMEG" is redetermined with the quantity of the goods movements (table AUFM).

• 0PM_OM_OPA_3: retrieve additional data from tables EKKO, EKPO, EBAN.
  It also determines an adjusted net due date (zznetdt) that corresponds to the delivery day (or the current date if the delivery date < current date) to which is added the terms of payment.
