Hello Joel,
SDM WS error messages are docuementated at this URL:
https://docops.ca.com/ca-service-management/14-1/en/building/building-ca-service-desk-manager/web-services-management/tips-for-soap-web-services-clients
::
UDS_BAD_PARAM | 1000 | A bad parameter was passed to a method. This error occurs if a required parameter is missing, the wrong type was passed, or an invalid value was used. |
There are some known patches for SDM 12.9 for problems qith the changeStatus function.
The user trying to used this WebService function must have administrator permissions.
I think it is best you active at the sdm server with pdm_log4j_Config the debug level and redo your test.
The jrsvr.log file with show the data for your ws call.
This will be the starting point to investig why the function is now working for you.
You may open a CA Support case to get help from ITPAM and SDM team.
