Hi Eli,
When I checked this note in SNOTE it shows an error that it cannot be implemented. How ever I came across note SAP note - 1984315:
If in one document line e.g. internal order AND cost center are posted to simultaneously, then one of those fields is statistical (let's assume the cost center). If the ledger has the 'FIN_CCA - Cost Center Update' scenario assigned, FAGLFLEXA-RCNTR will be initial, since due to conceptual reasons the new G/L line item table (and totals table) must not be updated with statistical dimensions (see also OSS note 964686). In this case the system would extract/display an initial value for cost center since the ledger has the 'FIN_CCA - Cost Center Update' scenario assigned and therefore it must take the cost center from FAGLFLEXA-RCNTR
