Hello Bernd!
I confirm that importing the root certificate is an administrative task that is always performed by specially trained and authorized employees in SAP systems. I expressly warn against not having such tasks carried out by the persons responsible for them, because an ERP system such as SAP is an extremely important part of a company and must be maintained and operated within the framework of regulations and laws. This is regularly checked by corresponding audits.
For this reason, I would like to refrain from providing detailed instructions on how to provide and import a certificate into an SAP system here in the forum. Incidentally, it would go beyond the scope of this article and SAP has created the corresponding documents itself and makes them available to its customers. If the SAP documents are not available or leave questions unanswered, other sources such as specialist publications and, of course, the Internet can be consulted.
In your answer, you mentioned 2035 as the expiry year. From this, one could conclude that the validity of the root certificate extends until 12/31/2035, 23:59:59. Unfortunately, the end of validity can occur on a random day and at a completely odd time. That's why I pointed out in my original post that the end of validity can come as a complete surprise.
I myself only use xServer Internet and not PTV-Developer. Therefore, I cannot say anything about the root certificate for the Developer. For xServer Internet, the validity (on the date of this post) is from 10/01/2008, 10:40:14 to 10/01/2033, 23:59:59, as can be seen in the attached screenshot of the SAP maintenance transaction STRUST.
