SAP Data Services: Session SDK Failure Error while installing SAP Information Steward


This blog refers to the Session SDK Failure Error which might occur at the SAP Data Services Designer Repository Login when installing SAP IS on top of SAP DS and SAP BI/IPS platform. The error popped when SAP IS Installation was triggered, everything had been working fine initially without SAP IS.

There are many solutions already provided to mitigate this issue. But when none of those solutions worked, there came a need to analyse the system in detail from the scratch. The problem is quite basic so at times may be overlooked or neglected. Thus, the purpose of this blog is to bring basics forefront and to highlight how this error is linked with the SAP IS installation.

Furthermore, the sections of this blog are divided as follows:

  1. Description of the issue

  2. Summary of analysis in terms of the various SAP KBA/SAP Note

  3. System Application Details: An example

  4. Root Cause

  5. Resolutions

  6. Abbreviations

Table 1. List of SAP notes related to Session SDK error

Sr. No. SAP KBA / SAP Note Description
1. 2151044 Could not reach CMS ‘hostname:6400’. Specify the correct host and port and check for network issues

The summary of the resolutions provided from these SAP KBA/ SAP note were (please refer to the Table 1):

  • Perform manual tests to verify if the issue lies in the network (for example: ping, telnet).
  • The request port between SAP DS client machine and the CMS server machine might be blocked by firewall or other network issues.
  • Ensure whether the CMS can be accessed.
  • The database, server name, port numbers, CMS name, must all be synced up.
  • SSL protocol have not been configured on Client machine in order to communicate with BI/IPS environment which one is using SSL for any communication with the CMS.

Note: But none of the above helped with the error. Please refer the following sections for the root cause and the resolutions.


C. Application Details: An example

Consider the above figure (Fig.3.) as an example of a High-level System landscape. It depicts the underlying Repository, the SAP IPS/BI, SAP DS, and SAP IS in a single stack.


D. Root Cause

After conducting all the analysis mentioned over the SAP Note and KBA’s. There came a need to start the analysis from the scratch and that’s when this compatibility check came in which are mentioned over in the following subsections Part 1 and Part 2. Please refer the SAP DS and SAP IS PAM guides for the reference.



Part 1:


Fig.4. Compatibility Check for SAP BI/IPS and SAP DS

  • From the above compatibility table (Fig.4.) for SAP DS and SAP BI/IPS, the SAP DS v4.3 SP0 P01 is COMPATIBLE with BI/IPS v4.3 SP2 P01.
  • So, there is no problem in the compatibility of SAP DS and BI/IPS.


Part 2:

  • From the below compatibility table (Fig.5.) for SAP IS and SAP BI/IPS, the SAP IS v4.3 SP01 P03 is NOT COMPATIBLE with BI/IPS v4.3 SP2 P01.
  • So, there is problem in the compatibility of SAP IS and BI/IPS.
  • And that is why when the SAP IS installation has been triggered, the SIA went down and everything was down in accordance.

E. Resolutions

Knowing the Root Cause of the issue, the following two resolution options are being suggested.

Option 1:

  • Restoring from the backup the SAP BI/IPS and SAP DS without the SAP IS installation process.
  • After this, choosing the compatible version of SAP IS.
  • But the only compatible version is SAP IS v4.3 SP00 and whose state is inactive.
  • The term INACTIVE means that, ‘This particular DS/IS version is no longer in active development in accordance with the DS/IS Maintenance Strategy’.
  • So, this will be again a decision to make whether to go forward with it or not.

Option 2:

  • Starting from scratch.
  • Planning for all the three components wisely i.e., SAP BI/IPS, SAP DS, and SAP IS. Their versions, their compatibility based on the dependencies.
  • Also, choosing the platform i.e., SAP BI or SAP IPS should be used (please refer to the documentation on SAP Help for further information on this).



Make sure to do the version compatibility checks for any installation.
