Define Cash Desk Structure
Application component: Contract Accounts Receivable and Payable
App type: SAP GUI
Description: You can use external cash desk services to transfer payments from your customers made at internal and external payment collectors (branches) to Contract Accounts Receivable and Payable (FI-CA). 
Key features: There are four branch categories in FI-CA: Offline branch without agent (category A)Agent offline branch with agent posting (category B)Agent online branch with G/L account posting (category D)Online branch In external cash desk services, you can process payments from branches of the categories 'offline branch without agent' (category A) and 'offline branch with agent' (category B and category D). For agents, there are two possible variants for posting closing. For an agent of category B, the cash desk closing is an agent posting (reconciliation in Contract Accounts Receivable and Payable). For an agent of category D, the cash desk closing is a G/L account posting (reconciliation in the general ledger). The cash desks of an online branch represent the cash desks of the cash journal in FI-CA. Here you enter and post incoming and outgoing payments directly in the SAP system and not by using external cash desk services. For the cash desks of online branches, you can also evaluate payments directly in the system as part of the scope of functions of the cash journal and execute follow-up postings such as deposits, withdrawals, differences, and reversals to the cash desk balance. In the case of the offline branch without agent (category A) or offline branch with agent (category B and category D), the cash desks where the payments are processed are not permanently connected to the SAP system. For both an offline branch without agent (category A) and an offline branch with agent (category B), FI-CA currently only receives XI messages that refer to incoming payments to external cash desks. Offline branches without agent (category A) and offline branches with agent (category B and category D) are represented by their own master data objects (see Customizing for Contract Accounts Receivable and Payable under Business Transactions  Payments  Processing Incoming and Outgoing Payments  External Cash Desk Services  Define Master Data for External Cash Desk Services). For an agent of category B, you have to create the agent as a business partner in FI-CA, and assign the cash desks to a contract account. For an agent of category D, for whom reconciliation takes place in the general ledger, you do not have to create the agent as a business partner in FI-CA, nor do you have to assign the cash desks to a contract account Note Data transfer for outgoing payments to external cash desks is not supported. The external cash desk services consist of the following enterprise services, whereby the transfer of the data between the SAP system and the external cash desk system can be synchronous or asynchronous using the SAP Exchange Infrastructure (XI). CashPointPaymentCreateNotificationThe asynchronous service CashPointPaymentCreateNotification enables sending payment information of an external cash desk to FI-CA. CashPointPaymentReverseNotificationUsing the asynchronous service CashPointPaymentReverseNotification, you can reverse payments previously sent. CashPointClosingDocumentNotificationFor reconciliation purposes, FI-CA can be provided with information for cash-desk closing by the asynchronous service CashPointClosingDocumentNotification. CashPointOpenItemSummaryByElementsQueryResponseThe cash desk uses the synchronous service CashPointOpenItemSummaryByElementsQueryResponse to query the open items of a business partner in FI-CA. CashPointOpenItemSummaryNotificationUsing a mass activity in FI-CA, you can send open items to cash desks asynchronously using the service CashPointOpenItemSummaryNotification.  From a technical point of view, all services are realized by means of XI service interfaces and are made available to the software component FI-CA by the XI content. You can download the XI content using the SAP Service Marketplace for the application component of your industry solution.
