Data management
Data management contains BW analyses which are described below. Analyses System size and Housekeeping potential are described in the Basis add-on chapter.
Data management analyses tiles
Busy and quiet times of queries and DTPs
The analysis provides an overview of busy and quiet times of queries and DTP loads which were executed on all InfoProviders on a monitored system. The heatmap shows a total number of queries, DTPs or their sum. You can chose these options in the combo box View. Data is aggregated by weekdays and hours and it can be filtered by specific InfoProvider or by analyzed period. This analysis can help you to find quiet hours e.g. for operations which need more system resources. Also the busiest hours can be examined and their content can be split into other less busy hours.

InfoProviders size
The analysis provides an overview of all InfoProviders in the system divided into 3 categories. Each category represents size of InfoProviders that correspond to a particular group. E.g. "10%" group represent first 10% largest InfoProviders and their corresponding size. By clicking on a bar, application will be redirected to "Top InfoProviders" analysis, where "Top %" filter will be applied accordingly.

The user You can switch to the table view for more detailed information where data can be downloaded into a CSV file for further processing.
InfoProviders by year
This analysis provides user with an overview of InfoProviders in the system. Two charts are displayed here:
- Distribution by InfoProvider type - displays whole system per InfoProvider type
- InfoProviders - objects in the chart are sorted by size by default and can be further filtered
Both charts always display last 4 years + all others merged into other group (e.g. 2013 and lower) based on amount of InfoProvider data that belong to the group. InfoProviders chart can be filtered using:
- Top % - displays InfoProviders that belongs to a particular filter, e.g. "10%" will display first 10% of InfoProviders,
- # of objects - specifies max. number of objects to be displayed
InfoProviders by year analysis chart
The user You can filter data and also switch to the table view for more detailed information where data can be downloaded into a CSV file for further processing.
It is possible to switch color mode of bottom chart to "Query usage". This colorizing mode groups data in InfoProvider by their respecting reporting usage. All data that were reported on less than 10 times are colorized with blue color and all data reported on more than 1000 times are colorized with red color. Warm data colorized with orange color belong to the category between these two threshold values.

distribution
These analyses provide information about how data are is distributed in the system InfoProviders based on a specified characteristic and based on how many times these data areas were accessed by reporting (queries). Number The number of Data Distribution analyses tiles is not set and is bound to distribution analysis tiles depends on the settings on the central system. By default the BW module is shipped delivered with only one predefined data Data distribution analysis. Analysis tile contains overview information of how many of analyzed InfoProviders do contain specified characteristic.
Data distribution tile
The Data distribution analysis tile displays the number of analyzed InfoProviders which contain the specified characteristic. The below figure displays temperature based data categorization which is a type of data distribution and is by default included in the package.

Data distribution analysis standard view
Columns that The columns number of queries and size of data areas depend on data distribution settings of particular analysis are data areas usage/size columnsa particular analysis. These columns are created based on specification of data groups for particular you specify in your analysis. See Appendix B: How to define data distribution analysis for details how data distribution and their respective data groups are defined /wiki/spaces/ITOA/pages/14700282 for details about how to define data distribution and it's respective data groups for analysis. Each of these column columns contains a sum (for sizes) and weight avarage sum (for usagethe use) of corresponding data area values that belong to them. Footer of table contains information how many . The footer of the table displays the number of records was already loaded to the table, . This number will be gradualy increasing gradually increase, as as you will be scrolling scroll down in the table.

Data size vs. query usage
BW objects data partitions scatter plot
The visualization shows the relationship between data access and size of InfoProviders divided by time characteristic (in this case, year) in form of a scatter plot. It can show user how many times were data (of corresponding year) of an InfoProvider accessed in reporting. Visualization summarizes displayed information in tiles on right hand side.

...
It is possible to click on the data in the plot area and user will be redirected to the other analysis called 'Query usage by country' with used filter based on the chosen data.
To distinguish between front-ends we are using handle type (field HANDLETP) of table RSDDSTAT_OLAP. Here is the list of possible front-ends that we are collecting:
Handle type | Front-end description |
CMD | BeX Web Application |
EXTN | External application (needs to be defined) e.g. Analysis office, BOBJ, Crystal reports |
XLS | Excel |
MDX | OLAP BAPI (MDX, XML for Analysis, OLE DB for Olap) |
BICS | ABAP BICS API |
W3_I, W3_T | Web templates |
BTCH | Batch Query |
PLAN | Planning |
PLPE | Planning via Planning engine |
We provide also possibility to define your custom logic for separation of front-ends that is based on handle type and you can define it by implementation of BADI "/DVD/HS_GET_QUERY_FRONTEND_USG".
