Understanding the Building Blocks of PAPM Models Through Functions

SAP Profitability and Performance Management (PaPM) system plays a pivotal role in financial planning, operational performance, and profitability analysis. While the tool is incredibly flexible, its modeling framework can be understood through a set of functions. Each function performs a specific task, and their coherent structure aids in seamless data flow and calculations.

When PaPM is installed on S/4HANA, it becomes part of an integrated ecosystem that further expands its capabilities.

When you integrate SAP Profitability and Performance Management (PaPM) with your S/4HANA environment, financial data management becomes more streamlined. Accounting records from the ACDOCA table can be seamlessly imported into PaPM for detailed analysis. Once processed or modified, these records can be written back to the ACDOCA table efficiently. This efficient data flow leverages PaPM features, notably the "information function", ensuring a sophisticated and optimized approach to financial data management in the SAP ecosystem.

Function Categories in PAPM

In the context of SAP PaPM and S/4HANA, let's take the scenario where ACDOCA (Accounting Document Table) data is to be brought into PaPM and eventually written back as an accounting document.

In PaPM, the different functions that are critical for building models fall under six categories. These are:

1. Information Functions

Information functions serve as the foundational layer that deals with the data and information model within an environment. They come in four types: Model BW, Model RDL, Model Table, and Model View. These functions act as proxies containing detailed specifications required to read and, optionally, write data to and from the model. Essentially, they define or display the available fields that can be manipulated or viewed within the model.

When integrating with S/4HANA, the requirement to bring ACDOCA (Accounting Document Table) within PaPM is typically fulfilled using Information Functions.

Example with ACDOCA

Information Functions

·?Scenario: Import ACDOCA data into PaPM for further analysis and calculations.

· Example: Utilizing the Information Function, say Model Table, to read data from ACDOCA table in S/4HANA and make it available for processing in PaPM.

2. Processing Functions

Processing functions are the workhorses of the PaPM environment. They take data from Information Functions and perform various operations like calculation, allocation, valuation, and derivation to produce an output. The output from one processing function can serve as the input for another, enabling complex data flows and calculations.

Processing Functions

·??Scenario: Apply certain calculations on the imported ACDOCA data. Perhaps you want to calculate the tax liability for each transaction.

·?Example: A Calculation function can be created that takes ACDOCA data (imported via Information Function) as an input and performs specific tax calculations.

3. Write and Adapter Functions

This category primarily deals with the output of data, either storing it back into the system or passing it to an external system for further processing. The Write function enables the writing back of processed data as accounting documents in tables like ACDOCA when integrated with S/4HANA. The Remote Function Adapter and File Adapter function type of export are also part of this category, which allows for data handover to external systems.

Write and Adapter Functions

·?Scenario: After processing the ACDOCA data, you need to write the calculated tax back into S/4HANA as an accounting document.

·?Example: Use the Write function to update the tax liability back into ACDOCA in S/4HANA. This makes the processed information part of your accounting records.

4. Query Function

Query function defines the display settings for a user. It sets whether the data should be read-only or editable. For editable settings, the input function has to be a Model BW function. This function doesn’t provide output to subsequent functions as it's mainly designed for data input and reporting.

Query Functions

·?Scenario: You want to provide users with the ability to view, but not edit, the newly calculated tax data.

·?Example: Implement a Query function that pulls this calculated data from the model and displays it as a read-only report to end-users.

5. Calculation Unit Function

Calculation Unit function provides a way to break down complex models into multiple units for easier manageability. For example, in a decentralized month-end closing process, different business units can have their independent processes and activities managed through individual calculation units. However, all the results can be aggregated and stored centrally.

Calculation Unit Functions

·?Scenario: Your organization has multiple business units, each needing to calculate tax liability differently based on jurisdiction.

·?Example: Use Calculation Unit functions to segregate the ACDOCA data by business unit, allowing each to run its own tax calculation process, while storing the results centrally.

6. Description Function

While it has no impact on the functional outcome, the Description function is used for documentation and explanatory purposes. It helps in improving the readability and understandability of the model.

Description Function

.?Scenario: For compliance and auditing, you need to document how tax liability is calculated from the ACDOCA data.

.Example: Implement a Description function that outlines the step-by-step process of how ACDOCA data is processed, calculated, and written back, aiding in future audits and compliance checks.

?Function Hierarchy and Process Flow

In a typical PaPM model, the Information Functions act as the starting point, funneling data into Processing Functions. The processed data can then be routed through Write and Adapter Functions for storage or transfer. Query Functions usually stand alone, handling user interaction, while Calculation Unit Functions help in process structuring.

Conclusion

Understanding these function categories and their roles is crucial when working with SAP PaPM models, especially in complex integrated systems like S/4HANA. Each function serves a specific purpose, and the ability to use them in combination allows for the creation of highly flexible and intricate models capable of addressing a wide range of business needs.
