SAP cloud platform Business Rule Service

I have created 4 projects in Business Rule editor for my HANA trial account. All projects are active and all the rules under each project are deployed and tested in POSTMAN but if I am trying to edit any of the rules, it’s giving an error “Validation for rule has failed, technical issue in rule expression parser validate service” while validation. Does any additional configuration is needed?

Please help.

    Hello Monika,

    No configuration is needed. If you check the rule, then one/more rows of the decision table expression would be showing the error.
    If you send across the screenshot of the error and the decision table - it would help. Also if you can separately send me your projects as well, I can quickly check the reasons for the error.

    Hi Archana,

    That was a temporary issue which got resolved by its own next day. Now I am facing another issue while invoking business rule. I have created a Fiori app to author a business rule by referring this blog ‘’ then there is an error with bpmrulerepository destination where I am not able to make a GET call.

    In bpmrulerepository configuration, I have tried with 'no auth', 'basic auth' and 'app to app'.

    Please refer attached screenshots.
