The Central Finance 1909 version and later have central payments functionality. This article shows us how to implement central payment capabilities without a central finance SAP environment. Two alternative SAP landscapes (SE1 and BABUEHP7) using a single SAP Central Payments system are demonstrated in this article (ECCEHP8). This article will focus on and limit the use of the internal cash centre in the Source system (Central Payment system).

Use Case

Tom is the head of the Treasury division for a US-based company that operates internationally from various nations. A global template for the Finance & Treasury process had been implemented by Tom’s company, and it has been operational since 2018. Recently, Tom’s business bought a new business in Europe. The company that was acquired used a SAP system that had been operational for the previous five years. Tom wants to make sure that the newly acquired company’s Treasury procedure adheres to the established framework. The business would be affected by any change, though, as the system landscapes varied and a sizable number of users relied on the current environment. Tom meets with his IT architecture Neeraja to offer a solution, so the newly acquired company may use a worldwide template without interfering with business operations.

Business need

Tom intended to use the current system with only minor improvements to either system. Tom is limited by his budget if he chooses the new S4 HANA product of Central Finance and Central Payments. Tom hopes to have the most recent version of the S4 HANA system with Central Finance features in the upcoming years.

Utilized SAP In-House Cash Solution in two distinct SAP environments by recently acquired company (SE1 & BABUEHP7). There are both internal and external payments. The business also used the POBO (payment on behalf of) procedure.

Tom intended to use the POBO process and the DMEE and BCM approval procedures that are currently used in the global template for payments (ECCEHP8).

Utilizing SAP

An answer has been found thanks to Neeraja IT architecture. By employing a remote function call, the two new system landscapes (SE1 and BABUEHP7) will connect to the central system ECCEHP8 (RFC). The books of sources systems account for the vendor/customer payments (SE1 & BABUEHP7). Using the current global template payment file structure and BCM approval process, payment to the vendor through the external banks will be carried out from the Central Payment system ECCEHP8. The central system ECCEHP8 will be used for accounting for payments.

Depending on the needs of the client, accounting entries may alter. In order to align with central payment processing while taking into consideration payment requests handled from various clients, all accounting entries presented in the blog are for representational purposes only.

The S4 HANA Central Finance solution’s central payments functionality is not replaced by this solution. The S4 HANA Central Finance solution’s central payment capabilities provides numerous additional functionalities (such as open item clearing options). Before deploying the SAP Central payments capabilities of S4 HANA Central Finance, the solution described in this blog can be viewed as a preparatory step.

The SAP sandbox systems SE1, BABUEHP7, and ECCEHP8 that are shown in the blog are unrelated to any clients.


Payment requests can be forwarded to another Central SAP client after being processed in a SAP client utilising the In House Cash process. The receiving SAP system is capable of processing payment requests (making use of single instance connections with external banks). the following advantages with centralised payments from several SAP systems

  1. In terms of connectivity, the central system relates to external banks (avoid multiple connections with banks)
  2. In a central payment system, there is only one DMEE (payment file structure).
  3. Centralizing the BCM approval procedure
