The following error message indicates that the problem is a server issue (and not a <CRM.pad> issue): "The action could not be completed because it was rejected by the server".
Check the server log file (in Debug mode with WebTrace) to identify the problem (especially when the user states remarks like "but in web it is working"). CRM.pad is not a web application, therefore functions may work in Aurea CRM web but not in CRM.pad
Compare Aurea CRM web statements with those from the CRMpad for differences. For example, some fields that are filled in web but not in CRMpad may cause the problems.
Enable the request and result log for information on the complete response from the server.
