When something from a data source is added to a data module, this metadata is added to the data module. This can help avoid unnecessary metadata callbacks to the data source. This metadata is stored and is used by Cognos in its query generation. In addition, Cognos attempts to determine the usage of the column and its aggregation. This metadata includes things such as the name of the object and, in the case of a column in a data source, the data type of the column. When either a schema is loaded, a file is uploaded, or a data set is created, metadata describing the columns and tables of the data source is generated. Query item is a column from a table in the data source. In addition, calculation refers to a stand-alone calculation. ![]() An uploaded file will generate something similar, with a table for each worksheet in the XLS-type file or, if the file is a CSV, a single table. A data set is a single table data base stored by Cognos. In this paper, the term data source refers to either a data base schema, an uploaded file, or a data set. The new update metadata functionality works similarly to the Framework Manager (FM) update object functionality. The refresh metadata will also refresh the metadata of objects which are used by the objects of the selection. The existing method, manually editing the expressions for each affected query item, is too lengthy and kludgy. Folders within a query subject will not be valid for this action. The objects which will allow you to select and refresh properties are the module, calculations, query items, query subjects, views or similar objects, and folders. You can also select multiple objects and update the metadata. These are properties of query items and stand-alone calculations.īy making a selection, you can update the query items of the objects which are encompassed by the selection by choosing the refresh properties menu item on the context menu. ![]() The metadata changes which will update are the data type, technical data type, aggregate, and usage properties. The refresh metadata functionality determines which property values of the data sources used by the selected objects have been changed and attempts to update the data module to pick up those changes. ![]() Starting in Cognos Analytics (CA ) 11.2.2, you can more easily update the metadata of your modules to match what is stored in the loaded schemas, uploaded files, and data sets which your modules use. ![]()
