Transaction ST13 provides specialized tools for evaluating SAP BW system performance. In Transaction SE38, choose Report RTCCTOOL > Execute. The results are shown in this figure.
You can also see the version from Transaction RSA1 by choosing System > Status > Choose System Data. The data is shown below.
Obtain the latest ST-PI and ST-A/PI versions from SAP Service Marketplace. Transfer downloaded files to your server, and extract them using the SAPCAR tool at the SID admin level. Access Transaction SAINT to load the package, and install ST-AP. Then, update ST-PI via Transaction SPAM for system stability, security, and compatibility with the latest SAP technologies, ensuring optimal performance for your SAP environment.
The first step for the readiness check is to refer to SAP Note 3061594 - “SAP Readiness Check for SAP BW/4HANA - Central Note.” This SAP Note introduces the essential data collection framework managed by the RC_BW_COLLECT_ANALYSIS_DATA report. Efficient scheduling of the batch collection job hinges on the Activity 16 authorization assigned to the user ID, specifically for object S_DEVELOP. This authorization ensures seamless execution of the collection job, fostering a streamlined data analysis process within the SAP environment.
SAP Readiness Check for SAP BW/4HANA accommodates various eligible releases for conversion:

Once you’ve downloaded the ZIP file, you can now execute the Note Analyzer report Z_ SAP_BW_NOTE_ANALYZER. With the downloaded XML file, when you execute the report as shown in the next figure, you have the following choices:
Run the report, bearing in mind that the process will require some time to validate the SAP Note. During this time, the system will verify the existence of the note and proceed to download it if it’s accessible. Upon completion, you’ll observe the note status displayed as green if it’s available or red if it isn’t accessible. You can see the result of the check in the next figure. Install the notes one by one in the same order. After the notes are implemented, repeat the XML checks multiple times until all the note statuses are green.
You can see that the XML with code scan was available. You can now upload the XML and install the required SAP Notes.
For SAP BW versions 7.30 and above, the readiness check includes a code scan. If your SAP BW version is below 7.3, you must independently execute the code scan report. We’ll now concentrate on SAP BW versions greater than 7.3. The following sections outline the process.
Once the steps in the previous section have been completed, you need to execute the SAP Readiness Check for SAP BW/4HANA in the production SAP BW system. The first step is data collection. Execute Transaction SE38 and run RC_BW_COLLECT_ANALYSIS_DATA in the productive client of the system scheduled for analysis, as shown below.
Click on Schedule Analysis to see the screen shown.
Click the checkmark button in the first figure to see the jobs status as shown in the second figure.
Once you’ve seen the list of active jobs, you can monitor when all the jobs are finished. If all the jobs are completed, go back to the readiness check report selections, as shown earlier, and click the Download Analysis Data option. You’ll get a popup to save the file.
After the file has been downloaded, you can see the details.
Once you’ve downloaded the ZIP file, the next step is to use this file and understand the details that will help to check for SAP BW/4HANA readiness.
