Error With MWS PUT API: "com.webmethods.caf.rules.osgi.services.impl.MergingException: Adding new rules is not allowed yet."

Hi

I am using webMethods 10.5 and looking to use the MWS APIs to update the decision tables. I can Lock, Unlock, Deploy, but when I try create a new row or delete a row, I get the following response back:

{
    "error_description": "com.webmethods.caf.rules.osgi.services.impl.MergingException: Adding new rules is not allowed yet."
}

Are there other APIs that I can use to add/delete rows in decision tables?

Hi Holger

I am calling the Save service to add 1 additional rule row. In the example below, I only had 2 objects in the “rules” array (ruleId 0 and 1). Now I am try to use the PUT API below to add 1 new object (ruleId 2). When I run the API, it returns the error in my post above. Previously I was using the webMethods browser MWS, but am exploring the use of the APIs instead to edit my rulesets.

I presume you are already following this document.

Can you provide your environment’s fix level and related __full__.log entries as well ?
