Solution for posting interface to integrate multiple systems with SAP Financial Accounting in S/4HANA or ECC

Trusted and reliable postings

Knowledge in central place

Easy maintenance & monitoring

Reduce TCO


Int4 Posting Templates is a dedicated solution for companies that perform operations in multiple non-SAP systems and use SAP Financial Accounting in S/4HANA, SAP ECC or SAP Central Finance to have a central view on all operations and up-to-date financial exposure.

Instead of building hundreds of separate application interfaces per external system and business operation int4 Posting Templates offers unique approach of building a comprehensive single posting interface engine. With configuration, not coding, int4 Posting Templates supports handling postings from multiple systems and multiple business operations.

Having int4 Posting Templates implemented is a simplification of the integration landscape and the TCO reduction. All the transactions are maintained and monitored in a central cockpit. This significantly increases trust in the system and reduce complexity. The solution is delivered together with a limited version of int4 IFTT, our product for test automation. Thanks to that all changes are always immediately  regression tested.

How does it work?

External systems are connected to SAP Backend by SAP PO or other middleware. The data is normalized and sent in a canonical data model to SAP Backend to the int4 Posting Templates engine.

Then the int4 Posting Templates identifies the scenario, perform enrichment and transforms business operations into valid financial postings.

Scenario determination and enrichment is based on configuration rules that are called posting document templates.

int4 Posting Templates can be pictured as a SAP S4/HANA internal integration between FI and other modules.

Key Capabilities of int4 Posting Templates interface

SAP testing - Minimal effort of creating test cases
Powerful options. Some examples: Mappings for GL accounts, profit centers. Settings for splitting criteriaor reflecting balance sheet counter postings.
SAP Complete testing scope
Configuration instead of coding. Business users without integration knowledge are able to add new business scenarios or change existing ones
Simplification – integration is no more a black hole
Single place of knowledge. All rules are kept in int4 FinTemp configuration tables and decision trees. It is easy to review all posting types and FI document templates to understand how exactly each process works.
SAP Business oriented tool
High performance, reliability and easy reconsilation

Solution Details

Due to its nature Int4 Posting Templates is a consulting solution. The predelivered content is deployed and it is adjusted based on company specifications. The solution is delivered together with implementation methodology.
One of the key factor for single posting solution for multiple systems is to build a common language and define all attributes that defines business operations and expected impact in financial system.
Therefore the canonical data model needs to be created.
Subsequently XSD schemas will cover all the requirements in single formats.
Depending on the situation external system should provide data in agreed format. Alternatively the SAP PO mappings can handle conversion from system dependent format into shared canonical data model.
Each business operations like sales invoice or material movement needs to be transformed into proper financial posting. They are not delivered as financial documents so It means that all specific settings need to be derived by int4 Posting Templates.
In this process the credit and debit side of booking will be build, GL and reconciliation accounts determined and splitting attributes applied together with many others defined rules.

Configuration matrix is a set of instructions for every posting handled by the interface. Business users, instead of changing PI/PO mappings or ABAP coding can easily adopt or create the new settings and handle new external systems and posting types.
When all design details are in place, it is the right time for implementation. Int4 Posting Templates is delivered as a preconfigured set of ABAP classes and transactions that allows implementing the dedicated solution quickly and efficiently comparing to a custom solution built from scratch.
Key principle for efficiency is re-use and avoiding logic duplication. This generates a need for regression testing. Our team use Test Driven Development approach which is supported by int4 IFTT, automated testing software, delivered in the package.

The transformation logic is implemented in ABAP in the SAP backend system. SAP PO or other middleware is used for simple format transformations. It means that the logic stays in only in one component.
This makes the solution easy to monitoring.
Solution might use both IDoc or SAP AIF messages to exchange data.
The Solutions that one element is used in many scenarios are more susceptible for unexpected actions. On the other hand this is a real accelerator to react promptly on business needs and adopt IT solution very quickly.
However after making a change in int4 Posting Template configuration we need to be sure that all other postings are working as expected.
For that purpose int4 Posting Templates is shipped with limited version of int4 IFTT, our interface testing suite. During the life-cycle each scenario has it is own set of automated test cases. Thanks to that every change in configuration logic might be immediately regression tested. There creates 100% confidence and trust for business stakeholders.
