Duet 1.5 Updates - New hotfix
Our team has been busy the last few weeks getting the latest patch for Duet ready for implementation. I have several minor updates to share in this general update.
Duet 1.5 SP2 HF1 Now Available
This is the latest patch for Duet and offers an expanded set of support and corrects some important issues in Duet. This patch became available last Friday June 19th. When applying the patch you must take care to remove the cache of existing Duet client as the default encryption of the local cache is removed with this patch. You can find details on this upgrade process and a revised client installation script @ the Microsoft Duet Community.
A recap of the product availability by patch level:

Installation Sequence
I am also revisiting the installation sequence requirements posted a few weeks ago. The following tables include the required client installation sequence to reach the current Duet 1.5 SP2 HF1 installation level. Again refer to the client installation script which already accounts for all of these steps in the installation script @ the Microsoft Duet Community.

Again we are working to simplify this installation procedure in a coming release so stay tuned for updates and we have already received plenty of customer feedback that we need to simplify this process.
Initial Installation Findings
I have already had the opportunity to implement the patch in a customer landscape. The biggest gotcha is simply missing the step to remove the local metadata cache before upgrading the client. If you do perform this action out of sequence no harm is done to the client however the user will experience an error immediately on start-up of the Duet utility as shown below.
This error is corrected by carrying out the “RemoveCache” option with Duet client repair tool. After the cache is removed restarting of the Duet utility will proceed with the configuration of the client.
Other things of note in this release is the re-enabling of the some of the detailed support options in the SAP Client support utility, providing you easy access to some of the CRT commands and sync monitor.
Also don’t forget to apply the update group policy template provided with the fix, this is provided with the SP2 HF1 KB. Of course we have additional patches on the SAP server to apply but nothing unique from an application procedure on the SAP side.
One change is the structure of the SAP documentation in the SAP Release Information notes. The OSS notes now delineate the Java/.Net fixes, which are simply provided in the SCA patches, form the actual ABAP notes which require application in the SAP system individually.
