Displaying the "Cost Flows Overview" Report 
Prerequisites
The Cost Flows Overview report documents the cost flows in Controlling as well as the reconciliation postings for CO-FI. This report displays all the cross-company-code, cross-business-area or cross-functional-area cost flows in Controlling. It consists of three blocks:
The SAP R/3 system displays the cross-company-code, cross-business-area and cross-functional-area cost flows in separate lists.
Cost flows can be cross-company-code, cross-business-area and cross-functional-area at the same time. Therefore, the system displays the cost flows in the overview list according to the criteria company code, business area, functional area of the sender and the receiver. The system also displays the adjustment account for the reconciliation postings.
In the detail list, the system can display, for each row of the overview list, the CO line items that caused the cost flow. It also displays the FI documents created with a reconciliation posting.

If you run the report on Cost flow overview for cross-company code cost accounting for one company code, then the total of all cost flows across all company codes, business areas and functional areas, and the total of the overview list does not equal zero.
The balance displays the costs that were allocated from different company codes to the one that was evaluated in the Cost flow overview.
If a part of the allocations affects all business or functional areas, then it is possible that the total of the cost flows across business areas or functional areas is not equal to zero.
If you run the report on Cost flow overview for cross-company code cost accounting for one controlling area, then the total of all cost flows across all company codes, business areas and functional areas must equal zero.

The SAP R/3 System includes in the reconciliation ledger internal CO postings that apply to all funds. These postings are also reconciled with FI.
Procedure
To call up the Cost flows overview report, proceed as follows:

The selection of the CO documents is very time consuming and should therefore be executed in the background.
The SAP R/3 system displays all documents from the reconciliation ledger for reconciliation postings, as well as the corresponding FI documents.

You can also display the funds that caused each cost flow.
If you have selected the Itemization display, and you are processing online, you can go from the Cost flows overview to the display of the appropriate document. To do so, place your cursor on the document number and choose Execute.
