How to create an input parameter to pass another corresponding value?

Hi Everyone,

I want to create an Input parameter in a way which will prompt the user to enter the value in some predefined description, but in back end it should pass the ID of that filed. I have a field call ERP System; the ERP system can be identified from ID or the name. Currently the users are entering the value using the ERP name. But to restrict the data from table used in view, based on ERP, I am joining using the ERP ID (as the fact and dimension tables doesn't have ERP name).

So my question is, if it is possible to accept ERP name in the front end and filter the table data based on ERP ID by passing the ERP ID internally?

I have WebI reports running on this view, so if I can achieve this from WebI also a fesible solution for me.

Note: I have one ERP Table, which stores the ERP Name and ERP ID column.

    One option to reach this is to use a second (hidden) parameter which parameter type is "Derived from procedure/scalar function".

    So you have two paramters:
    • Your original parameter in which the user enters the ERP name.
    • A second (hidden) parameter which uses a stored procedure or scalar function to determine the ERP ID from the entered ERP name.

    Following a dummy example which uses a stored procedure which returns an "id" dependent on a specific text (in that example the values are hard coded but can of course be determined out of a table).

    Procedure (consider that the output parameter must also be a string, if another type is required, then the conversion has to be done in the view):

    PROCEDURE "MISC"."test.misc.procedures::P_DERIVED_P_MAP_VALUE" ( in i_text nvarchar(100), out e_id nvarchar(4) ) 
    	--DEFAULT SCHEMA <default_schema_name>
    	if :i_text = 'test01' then
    	  e_id := '1';
    	elseif :i_text = 'test02' then
    	  e_id := '2';
    	elseif :i_text = 'test03' then
    	  e_id := '3';
    	  e_id := '9999';
    	end if;

    ID Parameter:
    This is the (hidden) parameter which receives the ID determined by the procedure. You have to map your first "name" parameter to the input parameter of the procedure.

    • Hi Florian,

      Sorry for replying late. The issue was really weird, when I created the same table in sys_bic schema then also it did not work. So I created a new table in its own schema and loaded the records from the existing schema, it worked. Though I could not figure out the reason of this.
