Custom parameters in URL with BexWeb (WAD/Web template)

Question

Hello all,
I've been reading a lot in this forum, but I haven't been able to do what I want to do.
I want to insert a custom parameter in the URL as we made with BW 3.5, and then read it.
I finally think it's something about the command SET_VARIABLES_STATE, but I cannon get it work.
In the template I have only been able to insert commands under the Web Template element (either before first display and before first rendereing, both with the same results). I've also tried several types of commands.
The XHTML generated is as follows:
                <bi:WEB_TEMPLATE_ACTIONS type="COMPOSITE" >
                    <bi:ACTION_BEFORE_FIRST_RENDERING type="COMPOSITE" >
                        <bi:INSTRUCTION >
                            <bi:SET_VARIABLES_STATE >
                                <bi:VARIABLE_VALUES type="ORDEREDLIST" >
                                    <bi:VARIABLE_VALUE type="COMPOSITE" index="1" >
                                        <bi:VARIABLE value="ZSESION" text="ZSESION"></bi:VARIABLE>
                                        <bi:VARIABLE_TYPE type="CHOICE" value="VARIABLE_INPUT_STRING" >
                                            <bi:VARIABLE_INPUT_STRING value="ZSESION"></bi:VARIABLE_INPUT_STRING>
                                        </bi:VARIABLE_TYPE>
                                    </bi:VARIABLE_VALUE>
                                    <bi:VARIABLE_VALUE type="COMPOSITE" index="2" >
                                        <bi:VARIABLE value="ZSESION2" text="ZSESION2"></bi:VARIABLE>
                                        <bi:VARIABLE_TYPE type="CHOICE" value="VALUE_SET_VARIABLE" >
                                            <bi:VALUE_SET_VARIABLE value="ZSESION2"></bi:VALUE_SET_VARIABLE>
                                        </bi:VARIABLE_TYPE>
                                    </bi:VARIABLE_VALUE>
                                    <bi:VARIABLE_VALUE type="COMPOSITE" index="3" >
                                        <bi:VARIABLE value="ZSESION3" text="ZSESION3"></bi:VARIABLE>
                                        <bi:VARIABLE_TYPE type="CHOICE" value="TEXT_VARIABLE" >
                                            <bi:TEXT_VARIABLE value="ZSESION3"></bi:TEXT_VARIABLE>
                                        </bi:VARIABLE_TYPE>
                                    </bi:VARIABLE_VALUE>
                                </bi:VARIABLE_VALUES>
                            </bi:SET_VARIABLES_STATE>
                        </bi:INSTRUCTION>
                    </bi:ACTION_BEFORE_FIRST_RENDERING>
                </bi:WEB_TEMPLATE_ACTIONS>
I pass it in the URL this way:
&BI_COMMAND_1-VARIABLE_VALUES-VARIABLE_VALUE_1-VARIABLE_TYPE=VARIABLE_INPUT_STRING&BI_COMMAND_1-VARIABLE_VALUES-VARIABLE_VALUE_1-VARIABLE_TYPE-VARIABLE_INPUT_STRING=010/2010&BI_COMMAND_1-VARIABLE_VALUES-VARIABLE_VALUE_1-VARIABLE=ZSESION
Also, I want to read it using the ABAP interface IF_BICS_CONS_WEBITEM_CUST_EXIT, method EXECUTE.
I wonder if it's possible that, once the command parameter works, that the value of my parameters arrives here in the I_XML in parameter.
I've also read about standard class CL_RSWR_SERVICES, but I don't really want to debug a std class and even less to enhace it ...
PD: This variable ZSESION does not exist in any query, and we don't want it to exist, as it's only necessary for integration in the intranet.
Thanks to all,
Rafa

Hi,
It is possible in 7.0, but unfortunately it is a lot more complicated than i 3.x. There are quite a few examples here:

I used it in a case where I wanted to embed a Web template in a BPS application and pass characteristic filters from the BPS application to the web template - similar to your requirements. Basically you need the following just to restrict one characteristic :o(
&BI_COMMAND_1-BI_COMMAND_TYPE=SET_SELECTION_STATE
&BI_COMMAND_1-TARGET_DATA_PROVIDER_REF_LIST-TARGET_DATA_PROVIDER_REF_1=DP_1
&BI_COMMAND_1-CHARACTERISTICS_SELECTIONS-CHARACTERISTIC_SELECTIONS_1-SELECTIONS-SELECTION_1=SELECTION_INPUT_STRING
&BI_COMMAND_1-CHARACTERISTICS_SELECTIONS-CHARACTERISTIC_SELECTIONS_1-SELECTIONS-SELECTION_1-SELECTION_INPUT_STRING=PDS06
&BI_COMMAND_1-CHARACTERISTICS_SELECTIONS-CHARACTERISTIC_SELECTIONS_1-CHARACTERISTIC=0D_PH2
I could only get it to work with one characteristic and I suspect, that the reason is that the URL simply gets to long (very quickly). You have to repeat the above for every characterstic you want to use :o(
