The presentation service can also send this error : Try to use the same letter case for the name of the variable (upper and lower). WHERE upper(SALESREP) = upper('valueof(NQ_SESSION.USER)'). This logical WHERE clause expands into a physical IN clause, as shown in the following statement: See "About Using Initialization Blocks with Variables" for more information about initialization blocks. Data Structure Unlike dynamic repository variables, however, the initialization of session variables is not scheduled. ), #business-intelligence-suite-enterprise-edition-obiee. Css For repository variable initialization blocks, when you open a repository in online mode, the value shown in the Default initialization string field of the Initialization Block dialog is the current value of that variable as known to the Oracle BI Server. It is also saved as the author field for catalog objects. A common use of these variables is to set filters for use in Oracle BI Presentation Services. In the logical table source TIMES Fact from the logical fact table Times, let's fill in the where clause with the repository session variable. In addition, you can use Expression Builder to insert a constant as the default initializer, such as Date, Time, and TimeStamp. This section contains the following initialization string examples: Example 19-1, "A SQL Statement When Site Uses Delivers", Example 19-2, "A SQL Statement When Site Does Not Use Delivers", Example 19-3, "A SQL Statement Joining Tables From Multiple Data Sources - When Using the 'OBI EE Server' Setting", Example 19-1 A SQL Statement When Site Uses Delivers. As with dynamic repository variables, session variables obtain their values from initialization blocks. If a semicolon must be included as part of a role name, precede the semicolon with a backslash character (\). Then, you explicitly define session variables for each source. Automata, Data Type Contains the global unique identifier (GUID) of the user, typically populated from the LDAP profile of the user. 1. Note that the recommended practice is to use application roles rather than Catalog groups. Oracle BI, Determines certain elements of the look and feel of the Oracle BI Presentation Services user interface. In addition, if an initialization block fails for a particular connection pool during Oracle BI Server start-up, no more initialization blocks using that connection pool are processed. (Apart from the obvious answer: it's a bug. a fiscal calendar) that you have stored in a Periods table, you can write the analogous SQL for that calendar. Session variables are created and assigned a value when each user logs on. Since you are going to be setting these date variables using physical SQL in initialization blocks, the SQL issued will be specific to the database platform you are using. Determines if the initialization blocks required for authentication are executed. This system session variable overrides a variable defined in the Users object in the Administration Tool. Trigonometry, Modeling OBIEE - How to set a server variable with the session type via a dashboard prompt (with a request variable) ? Contains the groups to which the user belongs. Used to enable or disable Oracle BI Server plan cache hits. To test initialization blocks (optional): In the Variable Manager dialog, double-click the initialization block. Scripting on this page enhances content navigation, but does not change the content in any way. Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. Key/Value Process (Thread) Url The Oracle BI Server uses the cached results for subsequent sessions. Example message: "The execution of init block 'A_blk' cannot be deferred as it is used by session variable 'PROXY'.". With the version 10.1.3.4, a warning is generated: But BI Server process it without problem. Not the answer you're looking for? The Use caching option is automatically selected when you select the Row-wise initialization option. Such directories begin with sk_. 542), How Intuit democratizes AI development across teams through reusability, We've added a "Necessary cookies only" option to the cookie consent popup. For example, here are dates as set by the default values in the prompt. Note: The Test button is disabled when the Use OBI EE Server option is selected in offline mode. Asking for help, clarification, or responding to other answers. For example, if a folder were called sk_companyx, the SKIN variable would be set to companyx. You should set the logging level to 2 for the administrator to provide the most useful level of information. This section contains the following topics: System session variables are used by the Oracle BI Server and Oracle BI PresentationServices use for specific purposes. System session variables have reserved names that cannot be used for other kinds of variables (such as static or dynamic repository variables and nonsystem session variables). "USER"), the syntax works. The names of system session variables are reserved and cannot be used for other types of variables. Distance CREATE TABLE OBIEE_PROXY_USER ( PROXYID VARCHAR2 (100) NOT NULL, TARGETID VARCHAR2 (100) NOT NULL, PROXYLEVEL VARCHAR2 (100) NOT NULL) Insert some data : Create Session Variables for Proxy Functionality (inside the repository) Modify the instanceconfig.xml File for Proxy Functionality Here comes the more tricky parts Names for all variables should be unique. The second case is where a session variable needs to be evaluated as a string. Legacy groups are mapped to application roles automatically. For example, suppose you want to create session variables using values contained in a table named RW_SESSION_VARS. Testing GUIDs for application roles are the same as the application role names. 3. Example message: "The execution of init block 'A_blk' cannot be deferred as it is required for authentication. I have defined non-system session variable, says ABC in RPD, and would like to use it in Answers. Why is the error occurring only for User B? If a SQL initialization string for that database type has been defined when the initialization block is instantiated, this string is used. Select Use OBI EE Server, and then perform the following steps: In the box, enter the SQL initialization string needed to populate the variables. Required for authentication. You can get this warning when you perform a check global consistency. Cryptography Note that the NQSSetSessionValues() stored procedure is not supported for use through the Issue SQL page in Oracle BI Presentation Services Administration. Expression Builder pastes it into the expression at the active cursor insertion point. The SKIN variable points to an Oracle BI Presentation Services folder that contains the nonalterable elements (for example, figures such as GIF files). For example, you could define a nonsystem variable called SalesRegion that would be initialized to the name of the sales region of the user. If you select this option, this initialization block must succeed for users to log in. variables is good where variable is bad. For Example the report looks like this Region VALUEOF (REGION) SALES North Some value from North Variable 100 The other two can not be addressed it seems, I have tried variations: The same goes for default selection type 'variable expression': the expected result is achieved when using @{biServer.variables['NQ_SESSION.STORENBR']}, yet no such luck using: @{biServer.variables['NQ_SESSION.SV_STORE_NBR']}, @{biServer.variables['NQ_SESSION. Click here to get started. This SQL contains two constraints in the WHERE clause: ':USER' (note the colon and single quotes) is the ID the user types when logging in. Contains the locale of the user, typically populated from the LDAP profile of the user. Used for Oracle BI Presentation Services. Select a discussion category from the picklist. This variable is typically populated from the LDAP profile of the user. You open initialization block B, and then specify that block A will execute before block B. See "Testing Initialization Blocks" for more information. Why must a product of symmetric random variables be symmetric? User A was able to login to OBIEE presentation and see assigned product ID's being filtered in the report. Session variables are created and assigned a value when each user logs on. In the Session Variable dialog, type a variable name. Unlike dynamic repository variables, session variables are not updated at scheduled time intervals. "ABC") but error message "The session variable, NQ_SESSION.ABC, has no value definition." Grammar This causes block A to execute according to block B's schedule, in addition to its own. The only way I can actually address the other two values to set the default value, is through the default selection type 'sql result', in which I look up the variable value using the dimension to which it refer: WHERE "dimension". The approach Ive used, which is not ideal but has worked for me, is to hedge your bets in the Select statements. But when User B logs in he sees below error , when running the same report, [nQSError: 23006] The session variable, NQ_SESSION.PRODUCT, has no value definition. You can edit Repository initialization blocks, or Session initialization blocks. You could then set a security filter for all members of a group that would allow them to view only data pertinent to their region. About Using Initialization Blocks with Variables, Associating Variables with Initialization Blocks, When Execution of Session Variable Initialization Blocks Cannot Be Deferred, Enabling and Disabling Initialization Blocks. Web Services The syntax is: WHERE COMPANYID=ValueOf (NQ_SESSION.RETAILERID) The second case is where a session variable needs to be evaluated as a string. Contains the time zone of the user, typically populated from the LDAP profile of the user. SELECT 'VALUEOF(NQ_SESSION.WEBLANGUAGE)' FROM DUAL I have set up a session variable initialization block to read in the variable names and values from my translated strings table with this SQL: select session_variable,translation from W_LOCALIZED_STRING_G where lang_id='VALUEOF(NQ_SESSION.LOCALE)' To create a session variable: In the Administration Tool, select Manage, then select Variables. The following example illustrates how to create and use a multi-source session variable: In the Variable Manager in the Administration Tool, select Action > New > Session > Initialization Block. Cube From the Data Source Type list, select one of the following types. In the left pane, select Initialization Blocks under Repository or Session, depending on whether you want to enable or disable repository initialization blocks or session initialization blocks. The SKIN variable points to an Oracle BI Presentation Services folder that contains the nonalterable elements, for example, figures such as GIF files. vegan) just to try it, does this inconvenience the caterers and staff? Example 19-3 A SQL Statement Joining Tables From Multiple Data Sources - When Using the 'OBI EE Server' Setting. In the View Data from Table dialog, type the number of rows and the starting row for your query, and then click Query. Security In the User/Application Role Permissions dialog, click the Data Filters tab. When defining a dynamic repository variable, you create an initialization block or use a preexisting one that contains a SQL query. Used for Oracle BI Presentation Services. Each query can refresh several variables: one variable for each column in the query. Dom Table 19-2 shows the table in this example. Data Science Function In the Administration Tool, select Manage, then select Variables. Failure to execute can occur if the wrong credentials have been defined in the initialization block, or if there is an error in the default initialization string.
