Answer 1

Use
The variable exit may not be executed or false data may be selected when executing a query that contains variables with the replacement path Customer Exit, filled dependently of the entry-ready variables. As a preemptive measure, you can control the dependencies with the parameter I_STEP.
Features
The enhancement RSR00001 (BW: Enhancements for Global Variables in Reporting) is called up several times during execution of the report. Here, the parameter I_STEP specifies when the enhancement is called.
The following values are valid for I_STEP:
·        I_STEP = 1
Call takes place directly before variable entry
·        I_STEP = 2
Call takes place directly after variable entry. This step is only started up when the same variable is not input ready and could not be filled at I_STEP=1.
·        I_STEP = 3
In this call, you can check the values of the variables. Triggering an exception (RAISE) causes the variable screen to appear once more. Afterwards, I_STEP=2 is also called again.
·        I_STEP = 0
The enhancement is not called from the variable screen. The call can come from the authorization check or from the Monitor.
Values of other Variables
When calling the enhancement RSR00001 (BW: Enhancements for Global Variables in Reporting), the system transfers the currently available values of the other variables in table I_T_VAR_RANGE. The table type is RRS0_T_VAR_RANGE and the row type RRS0_S_VAR_RANGE references to the structure RRRANGEEXIT.
This structure has the following fields:
Field
Description
VNAM
Variable name
IOBJNM
InfoObject name
SIGN
(I)ncluding [ [ or (E)xcluding [ [
OPT
Operators: EQ =, BT [ [, LE [[, LT [, GE [[, GT [, CP and so on.
LOW
Characteristic value
HIGH
Upper limit characteristic value for intervals/the node-InfoObject for hierarchy nodes.
Activities
A variable that is to be filled dependently of an entry-ready variable must never be filled in step I_STEP=1. Now you are at a position prior to the variable entry. Values have not yet been entered for the input-ready variables.
You can insert the following statements to force the variable to be executed with I_STEP=2 and not I_STEP=1.
CASE I_VNAM.

IF I_STEP <> 2.
RAISE no_processing.
ENDIF.
