Supplement FM Account Assignment
Application component: Contract Accounts Receivable and Payable
App type: SAP GUI
Description:  SAP supports the integrated use of Funds Management with SAP Contract Accounts Receivable and Payable, the industry component Utilities, and the industry component Public Sector Contract Accounts Receivable and Payable. For all other industry components that use Contract Accounts Receivable and Payable, the integration with Funds Management is supported in a customer project. The integration of Contract Accounts Receivable and Payable (FI-CA) and Funds Management (PSM-FM) enables you to forward actual data from FI-CA to PSM-FM on a totals basis and thereby manage budget planning. By doing this, you can map the areas of responsibility within your organization in a hierarchical structure, and control both the movement of financial funds (revenues and expenditures) as well as the budget at your disposal. Note You can only use Contract Accounts Receivable and Payable with Fund Accounting if Funds Management is active. Caution Note that moving revenue and expenditure postings to FI-CA can restrict the availability control function in Funds Management. For more information, see FM Availability Control in Contract Accounts Receivable and Payable. For more information about the possible uses of Funds Management, see Funds Management. 
Key features:  The figure depicts the functional relationships for updating document data in Contract Accounts Receivable and Payable in Funds Management, and Accounting.   Assigning an FM account assignment The integration with Funds Management requires that each document item in the document must be assigned to one FM account assignment. For manual document entry, you can fill these FM account assignment fields. If you do not make any entries here, the system automatically assigns the FM account assignments you defined in the derivation rules when you save the document. The derivation rules are especially required for documents created automatically. In any one document, the amounts for each FM account assignment must be cleared. For more information, see Derivation Logic for Funds Management (PSM-FM). Classification in FM categories and transaction classes Documents are saved in the header and item tables of Contract Accounts Receivable and Payable. The system classifies the business transactions for Funds Management at the same time. The document is assigned to a transaction class and each line item of the document receives an FM category assignment. The FM category for the line item determines whether this is relevant for Funds Management or not. For more information, see Funds Management Category. Summarizing line items in totals records Line items are summarized in totals records in totals table DFKKSUM before they are transferred to Funds Management and collected in an open reconciliation key. The summarization in totals records is determined according to FM account assignments and FM category, as well as other criteria, such as company code, G/L account, posting data, and CO account assignment. When you close a reconciliation key, it is prepared for the transfer to Funds Management (or general ledger). At the same time, the reconciliation key is blocked for other postings. For more information about processing reconciliation keys, see Creating Reconciliation Keys or Closing Reconciliation Keys. Transferring posting data You transfer update-relevant data in Funds Management by using the same program (RFKKGL00) that forwards the data records to the general ledger. You transfer the totals records for each reconciliation key. For more information about transferring posting data, see Transferring Postings to the General Ledger. Note Payment Matching between Funds Management and Accounting for posting data from FI-CA takes place per reconciliation key. You cannot match documents that are posted in FI-CA but that have not yet been transferred.
