We are happy to announce the availability of the flat file interfaces analysis as part of the integration analysis in SAP Readiness Check for SAP S/4HANA and SAP Readiness Check for SAP S/4HANA upgrades.
File-based integration provides the ability to exchange files with third-party or legacy systems that do not support messaging. A flat file interface (FFI) is a definition (or mapping) of a file to be processed. It identifies the data fields within the file. This powerful interface type enables application developers to access data from a file as they would handle a message or a page buffer. Flat file interfaces are part of many customers’ business processes, as they are easy to implement and allow the processing of huge amounts of data.
Key Features:

The setup of the flat file interface analysis view is aligned with the other interface types in the SAP Readiness Check integration view.
Detailed View
Figure 2: Flat file interface view
The detailed view for Flat File Interfaces shows the total number of flat file interfaces, and the trace runtime.
There are four filter options available to adjust the result list items in the view:
The Impact Analysis chart and table subsection provide an overview of discovered interfaces and the results of the impact analysis performed by SAP Readiness Check. The analysis focuses on the most critical impact types that require immediate action during a system conversion.
Understand how flat file interface discovery works
Flat file interfaces are not centrally managed in an SAP system in contrast to other interface types, for example, IDocs or OData services. Therefore, a special method is needed to identify file interfaces of an analyzed system:
Figure 3: Overview of the data collection process for the flat file interface analysis
To keep the data volume as low as possible, SAP standard interfaces (e.g., transport system interfaces) are filtered out and not displayed in the results list. However, these interfaces can be reviewed within the flat file interface tool.
To activate the aggregated authorization trace and start the file interface discovery tool, follow the steps described in SAP Note 3322944 - File interface discovery for SAP Readiness Check
When to perform the analysis
The flat file interface discovery is decoupled from the rest of the SAP Readiness Check analysis. The data collection phase for the flat file interfaces does not interfere with or extend the execution runtime of other SAP Readiness Check data collectors. The data collection can be performed either before or after running the other SAP Readiness Check data collectors. The analysis interval of the authorization trace defines the precision of the analysis results. The recommendation is to run the trace for at least one week, or better for a month.

The flat file interface analysis data can be added to an already existing analysis within the SAP Readiness Check cloud application and it can be refreshed periodically by downloading a new export and uploading it again to the same analysis.
