Determine the selection values for the InfoPackage in the Data Selection tab page.
You can determine selection boundaries not only for InfoObjects mapped in the transfer structure, but also for unmapped fields in the source system. The fields are displayed in the Technical Name in Source System Displayed column in the selection table. To distinguish between InfoObjects and fields when selections are displayed, the fields are shown in brackets (for example, the display of the initialization selection for source systems in the Scheduler).
You can either enter single values or intervals directly in the from value and to value fields or set the selections as variable. You can find additional information underVariable Change of Selections with Background Processing.
When using selection criteria, InfoObject or field data corresponding to the selection limit is requested from the source system. With InfoObjects or fields for which no variable selections were determined, all available data is requested from the source system.
You can specify several selections for an InfoObject/field in which you insert duplicate rows. Additional rows for entries in this InfoObject/field are then inserted into the selection table. When selecting individual value- or interval selections and not confirming them, you can select an additional variable selection type in the same row of the InfoObject/field. The system automatically adds an additional row in the selection table for this selection. This ensures that your selections for an InfoObject or field are displayed in a clear format.
Selection options for DataSource from SAP source systems
When using a DataSource from an SAP source system, the DataSource determines which selection options are possible. All DataSources permit
Note that additional selection options are only possible if they are supported by the respective DataSource.
You can specify model selections (l_t_range-option = 'CP'), such as ABC*, in the field From Value as a single value. Note the following:
If you execute a selection with * in the From Value field, and the To Value field is not filled, check the scheduler to see if the DataSource allows the selection option CP. If this is the case, the l_t_range-option is changed from EQ to CP. If this is not the case, the scheduler returns an info message and passes the data request with the selection option EQ to the source system. If you fill the field To Value, the scheduler always passes the data request with the selection option BT to the source system and does not execute any check. The request is not cancelled in these cases.
You can also specify selection options for the data request by means of a routine or a variable. If a selection that is not supported by the DataSource is transferred from a routine or variable to the scheduler, the entire request is cancelled.
You can find additional information about selection options with routines and variables underVariable Changes for Selections in the Background Processing.
You can display the selection options supported by your DataSource in the source system in the data browser (SE16). Specify the ROOSFIELD table and choose Table → Table Contents. The SELOPTS field includes the value that the combination of selection options supported by the DataSource characterizes. For more information, see the F1 help for SELOPTS.
Selection Limits for Data from File- and External- Systems.
It is also possible to determine selection criteria for data from files and external systems. Only records that meet the selection criteria are loaded.
To specify field selections in the Scheduler, first select them in the Selection column in the transfer structure maintenance screen. Next, save and activate the transfer structure.
By specifying the selection criteria, you can execute the functions Automatic Deletion andChecking Data Consistency of the Requests in the InfoCube for data in files and external systems.
Selection limits for updating from an ODS object
If you want to update data from an ODS object into additional data targets using full-update, you can set selection criteria for scheduling.
When entering the selection, the conversion exits displayed in the selection table are executed in the OLTP and the results are temporarily saved in the BW. If a selection has already been converted, it is in the BW; if it is not yet in the BW, conversion takes place in the OLTP.
If conversion cannot take place in the OLTP, because the system cannot be accessed or the OLTP conversion exit is not running properly, conversion takes place in the BW. If this is not possible either, the Conversion Exit field is ignored, meaning that the selections must be entered in an internal format. In this case, entering in external format will lead to errors in the loading process.
If you have set the Use Conversion Exit option, the system adds two spaces to the length of each input field that has a conversion exit (except ALPHA exit). You can then use the external format (which is usually longer than the internal) in these fields.
If you want to deactivate the conversion exit in general, remove the Use Conversion Exit selection. Here, enter the selections in an internal format too. The system then takes the two additional spaces, that would have been needed for the external format, away from the length of the input field..
If you reload data from an archive file, select your archive file by using the pushbutton Archive Selection. For the time being, you can only load archive data within the BW.
