Steps to Reproduce
- Create a service in Pega 7.1.5 instance. This connects to an external database to fetch data.
- Create work objects using Pega 7.3.1.
- Run the service.
Root Cause
This behavior is as per Pega product design.
The work objects are created on Pega 7.3.1 with Storage Stream (BLOB) version 7. The SOAP service is configured on a Pega 7.1.5 instance with Storage Stream version 6. The Storage Stream version 6 can only read work objects of that version. Therefore, the service is unable to read work objects from another application that is running on Pega 7.3.1.
Resolution
Perform either of the following local-changes to open work objects:
- Upgrade the application with SOAP service configured to Pega 7.1.8 (with Storage Stream version 7) .
- Change to Storage Stream version 6 in Dynamic System Setting for the application running on Pega 7.3.1.
