For detailed information on the data-driven test types that are available in Silk Central, see Atomic and Non-Atomic Data-Driven Tests.
The default limits can be modified, if required. Modify these values with care though to avoid excessive data generation. Before attempting to modify these values, stop the application server and restart it again after you have saved your changes.
The row limits for atomic and non-atomic tests can be configured in the TmAppServerHomeConf.xml file. The default path for this file is C:\Program Files (x86)\Silk\Silk Central 20.0\instance_<instance number>_<instance name>\Conf\AppServer on the application server. Modify the values of the Config/DataDriven/MaxRowsAtomic and Config/DataDriven/MaxRows XML tags, respectively.
The XLSX cell limit can be configured in the configuration.properties file in the Excel data source plugin (DS-Excel.zip). The default path for this file is C:\Program Files (x86)\Silk\Silk Central 20.0\instance_<instance number>_<instance name>\Plugins on the application server. Modify the value of the excel.importcelllimit property accordingly.
