Click New Query and a dialog box will appear, giving the option of choosing whichever InfoProvider we want. The Select InfoProvider window is similar to those seen before: there is a History of recently seen Objects, a Find section, and also the opportunity to use the system hierarchy of the Info Areas to navigate and find the information we want.
After navigating through the Info Areas, there will be a number of InfoCubes, signified by the cube icons. DSOs would be represented with cylinder icons, and MuliProvider would have an icon showing cubes stacked upon each other. In the screenshot above, there are three identically named Cubes, and so the Technical Names need to be visible.
To do this, select the Display Object Name As icon the wrench , and select from the options available. With the Technical Names visible, it becomes easier to determine which InfoCube is required. Double click to Open it. The Find tool on the sidebar looks and acts just as in the BEx Analyzer, and allows wildcard searches that search both Descriptions and Technical Names.
Once loaded, the InfoProvider will be loaded into the Query Designer. You can see there are three high level folders: Structures, Key Figures and Dimensions. Dimensions is the name given to high level folders in InfoProviders. These are not Fields, but still high-level Containers containing Fields. To add this Characteristic to the Report, you must first find it. Click on Rows and Columns, and drag the Characteristic across to where you want it. Once the mouse is released, it is added into the Report. Once added, a small Preview appears showing the layout of the Report as it currently stands.
Clicking Save for the first time will open a window asking for a Description and a Technical Name. For the latter, your technical team should let you know the naming conventions of Queries saved into the System. Spaces are not allowed in a Technical Name. You can then open the BEx Analyzer and see how it displays.
This will be explained in detail later in the book. A Calculated Key Figure is a Base figure with a calculation or formula applied to it, whereas a Restricted Key Figure is a Base figure with an applied filter. These will be expanded on later on. To add a Key Figure, find the one you want to include in the list and drag and drop into the Columns window. When opening a newly saved Query in the BEx Analyzer, it is important to note that if the report was left open, refreshing the Query will bring back the old results.
This means that the design of the Query will only be refreshed if it detects the user is logging on for the first time, or if the session is closed and reopened. So, if you have made a change to the Query and want to view it in the BEx Analyzer, always make sure to disconnect from the system , connect up again and then refresh your data. If you want to make a change to the Query without opening a separate session, it is possible to access the Query Designer through the BEx Analyzer. Once you have run a report within the Analyzer, the Query can be edited by selecting the Edit Query menu option, either within the Tools icon on the toolbar or through the menu bar.
Once it is opened, it is not possible to go back to the Analyzer without closing the Query Designer.

While this can be an occasional pain, it does ensure that every time the Query is run after editing through this option, the whole page is refreshed. Hierarchies are a feature that can help structure Queries, add handy features, and alter the look and feel of a report. Key Figures can be structured to form a hierarchy.
To arrange Key Figures within a hierarchy, drag the fields up or down into the order that you require.go here
Compare two tables in Access and find only matching data
A horizontal line will appear to show where the field will appear when dropped. This can be a useful tool if you want to have columns that break-down a Key Figure further. Some Characteristics can also have a hierarchy attached to them. Give the description of the query in the next screen.
Specify the output length and select the processing option from the Further Processing Options box. The data can be displayed in various formats such as table, download to a file, and display in Word etc. Step 3. Click on the next screen, select the field group to be used.
Step 4. Click on the next screen, select the fields you want displayed Step 5.
On the next screen, select the selection fields and then chose one of the output types basic, statistics, ranked. In each of the lists, you can select various options. Sort order of fields, change output length, column color,totals,page header, page footer etc. Step 6.
Compare two tables by using joins
After providing all the above options you can save the query and execute it. This tool maps the key business functions of an For the example, create a row structure that corresponds to the selected fields of your dynamic SQL clause. The dynamic SELECT clause can be created from a string object or from a table with one column that contains the field names. You need to create a type description of each requested field from the SELECT clause and put the type descriptions into a structure description.
You will then use this structure description to instantiate the target structure type and then a target structure instance.
Steps to Create SAP HANA Application
This indirection is needed because a structure field needs both a type and a unique name, similar to the way a structure type is normally specified statically in ABAP code. Note that a field name must start with a character, and it cannot include any special characters. This means that you need to prefix the row index with a character.
There are multiple ways to create a type description for an ABAP type. However, you do not have a data object yet. You have only the name of the field in Open SQL notation. This function can take the name of an object. You want to have the description of the type of a database table column. Similar to the way data objects of a database field type can be instantiated in ABAP, Listing 7 shows the input of this function. The method creates the description object in memory and returns a reference to the object. Instead, ABAP provides field symbols of any type that take the place of a data object.
You now have a data object of a structure that has a field of the correct type for each field you want to select dynamically. This gives you all parts needed for dynamic joins that you can integrate into a working function module. This article does not provide step-by-step instructions to create RFMs because there is ample documentation available for this see Related topics.
However the parameters of the module and the source code are provided in the following sections. The example RFM will contain four table parameters. Three parameters provide the dynamic SQL clauses, and one parameter returns the selected data.

Before activating the code, create two structures representing the data type of the function-module's input and output parameters. Each of the following structures is based on an existing data element:. Word wrapping is not needed if the table rows in the ABAP code are concatenated. If you use the original database table in the dynamic ABAP clause, there would be some restrictions, such as field names not permitted to be split between rows.
Clauses that are longer than 72 characters need to be split into pieces of 72 characters and added to the corresponding INPUT table. The table name needs to be added even if the FROM clause doesn't contain joins so you can instantiate the correct field types.
To keep the example simple, assume that the data return code has the following restrictions:. Listing 10 shows the ABAP code of the function module. The code works in three basic steps:. For each returned row, the field values of the dynamically created target structure are cast into a string and concatenated with the separation character. The complete row representation is then added to the output DATA table.

These parameters are passed in the form of an internal table that is basically a two dimensional, in-memory structure with fixed row length. Note that although the use of table parameters is discouraged by SAP in recent system versions of the ABAP development environment, it is a common mechanism for passing structured objects to ABAP routines. The method extractTableData For the example scenario, the ABAP function module passes rows in the form of strings where fields are concatenated into a string and separated with the character , as shown in Listing To complete the example, Listing 13 shows the main method that takes the name of a file holding the SAP connection parameters as input, establishes a connection to the SAP system, invokes the remote function module, and displays its result on the screen.
The Open SQL clauses are provided as constants. The main method has a single vm argument, which must be the name of a file that contains connection parameters of the SAP system in the format required by the SAP Java Connector for details, see Related topics to review the definition of class DestinationDataProvider in the JCo user guide. The file should have the extension. Listing 14 shows content of the.
