Default Variables for Web Applications 
Default Variables for Web Applications
Use
Variables play a central role in BW queries. For example, the entire query or only individual parts of the query can be filtered before reading data according to values. There are variables with automatic substitution, substitution from authorizations, or variables that are ready for input.The variables for Web applications can be processed in the background (without a variable screen) or in the foreground (with a variable screen). In both cases it is desirable to predefine variables through parameterization. Therefore, all types of variables that are ready for input are supported
In contrast to filtering, the external value for predefining has to be specified for the variables. The date, for example, is transferred as it has been entered.
Features
You set default variables by parameterizing the URL. The variable values are separated from each other by different indexes.
The index in the parameter is indicated in the following by '_I'.
Characteristic Value Variables
Parameter variables or variables for several single values are predefined as follows:
|
Parameter |
Description |
|
VAR_NAME_I |
Technical name of the variables |
|
VAR_VALUE_EXT_I |
Attribute value in external display Key for characteristic value in external display |
Interval variables are predefined as follows:
|
Parameter |
Description |
|
VAR_NAME_I |
Technical name of the variables |
|
VAR_VALUE_LOW_EXT_I |
"From" characteristic value in external display Key for characteristic value in external display |
|
VAR_VALUE_HIGH_EXT_I |
"To" characteristic value in external display Key for characteristic value in external display |
Selection option variables are predefined as in the following:
|
Parameter |
Description |
|
VAR_NAME_I |
Technical name of the variables |
|
VAR_OPERATOR_I |
Operator 'EQ' = Individual value 'BT' = Interval 'LT' = Less than 'LE' = Less than or equal to 'GT' = Greater than 'GE' = Greater than or equal to |
|
VAR_VALUE_LOW_EXT_I |
"From" characteristic value in external display Key for characteristic value in external display |
|
VAR_VALUE_HIGH_EXT_I |
"To" characteristic value in external display Key for characteristic value in external display
This value must only be specified with VAR_OPERATOR='BT'. |
|
VAR_SIGN_I |
Row effect 'I' found values are added, 'E' found values are removed. |
Variables for precalculated value sets are preassigned as follows:
|
Parameter |
Description |
|
VAR_NAME_I |
Technical name of the variables |
|
VAR_VALUE_EXT_I |
Name of value set |
Variables for Single Hierarchy Nodes or Variables for Several Hierarchy Nodes
|
Parameter |
Description |
|
VAR_NAME_I |
Technical name of the variables |
|
VAR_VALUE_EXT_I |
Node key in external display Key for hierarchy node |
|
VAR_NODE_IOBJNM_I |
Name of the node characteristic With characteristic nodes and text nodes, you have to specify the characteristic name (0HIER_NODE). |
Hierarchy, Formula, and Text Variables
|
Parameter |
Description |
|
VAR_NAME_I |
Technical name of the variables |
|
VAR_VALUE_EXT_I |
Hierarchy name, formula value, text |
Examples
Predefining the parameter variable
http://yourAppServer:yourPort/SAP/BW/BEx?CMD=LDOC&template_id=yourTemplate&var_name_1=myParameterVariable&var_value_ext_1=4711
Predefining the parameter variable (4711) and select options variable (1, 7 to 12)
http://yourAppServer:yourPort/SAP/BW/BEx?CMD=LDOC&template_id=yourTemplate&var_name_1=myParameterVariable&var_value_ext_1=4711&var_name_2=mySelOptVar&var_operator_2=EQ&var_sign_2=I&var_value_low_ext_2=1&var_name_3=mySelOptVar&var_operator_3=BT&var_sign_3=I&var_value_low_ext_3=7&var_value_high_ext_3=12
Predefining hierarchy nodes variable (DE, 0HIER NODE)
http://yourAppServer:yourPort/SAP/BW/BEx?CMD=LDOC&template_id=yourTemplate&var_name_1=myHryNodeVariable&var_value_ext_1=DE&var_node_iobjnm_1=0HIER_NODE
