SAP is making SAP Notes more secure by ensuring all SAP Notes are digitally signed. The SAP Notes files can get maliciously modified and the customer unknowingly can upload the maliciously modified SAP Notes files into their ABAP systems. Therefore, SAP plans to deliver all SAP Notes files with digital signature to protect SAP Notes files with increased authenticity and improved security. We strongly recommend customers to upload only digitally signed SAP Note files.
Post January 1, 2020, the download and upload process will stop working unless Note Assistant (SNOTE transaction) is enabled in ABAP systems to work with digitally signed SAP Notes.
The digitally signed SAP Notes are available as SAR files. All SAP Notes downloaded through SAP ONE Support Launchpad are digitally signed SAR files.
- To enable Note Assistant (SNOTE) for downloading and uploading digitally signed SAP Notes, please implement SAP Notes 2408073, 2546220 and 2508268.
- An equivalent Transport-Based Correction Instruction (TCI) is available as SAP Note 2576306 containing the SAP Notes 2408073, 2546220 and 2508268. If the Note Assistant in your ABAP system is enabled for TCI, It is recommended to implement TCI SAP Note 2576306 instead of applying the above individual SAP Notes.
The Note Assistant tool will use the SAPCAR utility on the application server to verify the digital signature of the uploaded SAP Note. Please ensure required patch level of SAPCAR executable is available on your system. If not, the digital signature verification fails and the files are not extracted. Once you have implemented the above SAP Notes, you may test the working of upload of digitally signed SAP Note feature by uploading a sample SAR file attached to the SAP Security Note 2408073. Further details about enabling Note Assistant to support digitally signed SAP Notes are described in the user guide attached to the SAP Security Note 2408073.
Watch out the Note Assistant Page on SAP Support Portal, for the latest updates.
