Question

I have a little challenge. I have a report that I declared a parameter called Department that has default values like this:

All Departments, Project, Field Service, Workshop, Warranty, Marine, Contract, Manufacturing.

Each department has database entry by which I grouped then in departments e.g
Field Service has [“JOB – EXT”, “JOB-AFMEXP”, “JOB-LUB/S”, “JOB-NBCMTU”,”JOB-ABB-AS”]

I have also enabled the “Allow Multiple Values” check box.

In my select expert, I have:

{command.Job Posting Group} in 
switch(
   {?Department} = "All Departments",["","JOB - EXT", "JOB-AFMEXP", "JOB-LUB/S", "JOB-   NBCMTU","JOB-ABB-AS","JOB-CANPJB",
                 "JOB-INSTAL","JOB-CUMNS", "JOB-W/SHOP", "JOB-WS/GEN","JOB-WTY","JOB-MAR","JOB-S/AGR", "RENTAL"],
{?Department} = "Project",["JOB-INSTAL"],
{?Department} = "Field Service",  ["JOB - EXT", "JOB-AFMEXP", "JOB-LUB/S", "JOB-NBCMTU","JOB-ABB-AS"],
{?Department} = "Workshop",  ["JOB-CUMNS", "JOB-W/SHOP", "JOB-WS/GEN"],
{?Department} = "Warranty",["JOB-WTY"],
{?Department} = "Marine",["JOB-MAR"],
{?Department} = "Contract",["JOB-S/AGR"],
{?Department} = "Manufacturing",["JOB-CANPJB"]
)

The problem is that when I test this (with CR10 or on web), and I select multiple values, the thing does not show the values for the multiple values. It only works when I select a single department.
What should I do?

I toiled for a while b4 I came up with this solution (Thanks to some friends and Ryan who made me remember that switch wont work.):

I first created a parameter field called {?Department}, then wrote a function called {@Dept} like this:

if {command.Job Posting Group} = "JOB-WTY" then
   "Warranty"
else
if {command.Job Posting Group} = "JOB-MAR" then
    "Marine"
else
if {command.Job Posting Group} in ["JOB-CUMNS", "JOB-W/SHOP", "JOB-WS/GEN"] then
   "Workshop"
else//etc.

I did not add an “All Dept” option to the formula. since I will do this programatically in the select expert like this:

(
   (
      {?Department} <> "All Departments" and {@Dept} = {?Department}
   ) or
      {?Department} = "All Departments"
)
