Purpose
The target of the document interface is to periodically transfer postedpayment requests (vendor documents) from the component FundsManagement to the component Contract Accounting for Public Sector
.
During document transfer, the payment requests are cleared in componentContract Accounting for Public Sector under a new document numberand the old documents in the component Funds Management arecleared.
After a successful transfer, the documents can be transferred to thecomponent Contract Accounting for Public Sector with the paymentor made payable on the cash desk.

Integration
If you want to use this document interface, you must have installed thecomponent Funds Management from the SAP R/3 Enterprise PublicServices Release 1.10 as well as the component Contract Accountingfor Public Sector starting from version 4.64. There must be a linkbetween these two components via ALE and the master data (businesspartner, G/L accounts, commitment items, commitment items, funds centers
, and so on) must be reconciled.

Prerequisites
The following restrictions apply for each FI document when transferring:

• The document can only have one vendor line.


• The document cannot have any customer lines


• The document cannot have a partial payment.


• The document cannot have payment share.


• When posting in Contract Accounting for Public Sector no partner
data is copied.

Features
A reconciliation key is first created using ALE in the componentContract Accounting for Public Sector of the target system. Thereconciliation key is either specified by the user (entry in thereconciliation key field) or generated automatically by the program(reconciliation key field stays empty). This reconciliation key cannotexist in the selected target system.
The open payment requests or deductions are then selected from tableBSIK in accordance with the selection criteria for selecting vendordocuments, and are then checked to make sure they meet restrictions.
User-Defined Enhancement for Data Transfer
SAP provides the event P200 which you can use to change openpayment requests during the transfer. To use this function, you have toprogram a function module with the changes you want. Then you enter thisfunction module as an installation-specific module in Customizing ofContract Accounts Receivable and Payable in the IMG activityDefine User-Specific Function Module<. You can find informationon the interfaces in the sample module FMCA_SAMPLE_P200.
SAP provides the event 0030 for Swiss customers. This canbe used to copy the data for the POR payment note. If you want to usethis function, enter the function module FMCA_EVENT_0030 as aninstallation-specific module in the IMG activity DefineUser-Specific Function Module in Customizing of Contract AccountsReceivable and Payable.
Each successfully checked payment request or deduction (vendor document)is transferred to the component Contract Accounting for PublicSector of the target system through ALE and posted there under a newdocument number after the conversion of certain key fields. A contractobject is created with the same key for the cash reference number of thepayment request automatically.
After the document has been posted to the component ContractAccounting for Public Sector of the target system, it is written offin the component Funds Management. The posting date entered isused for the write-off.
The posting in component Contract Accounting for Public Sectorand the write-off in Funds Management occur on the G/L accountthat you entered for the vendor document interface in the Customizing ofContract Accounting for Public Sector (target system). This G/Laccount is cleared again through the transfer process of totals recordsto component Funds Management.

Output
A log of the transferred documents is created and displays any warningand errors that occurred. You can access this log afterwards by enteringthe reconciliation key and calling the Display Log function.
An evaluation of all logs is possible using transaction RDCA_WIZ.
