SQ Server 2008 r2 Reporting Services : optional parameter values and reports -


in existing ssrs 2008 r2 report, have requirement user want add 2 more parameters report. right there option

where user can choice generate report1, report2, report3, report4, report5, report6, report7, report8, and/or combination of reports listed.

this setup using expression in visibility property each of 8 tablixes.

for information, following example of how display 1 of reports or not:

=iif(instr(join(parameters!report.value,","),6)>0,false,true)

now user wants able add parameters of customer , inventory_item based upon if report7 and/or or report8 selected.

now can tell me following:

  1. would show me code can use in dataset select report7 and/or report8?
  2. is considered using 'optional' parameters since new parameters of inventory_item based upon if report7 and/or or report8 selected. if so, can show me how can code these optional parameters?
  3. if above not possible select specific reports, dataset query need like: where @report null or @report not null? suggest?
  4. if above options not possible 2 new parameters, have items (or 1 item)selected reports run time?

for parameters, can check out cascading parameters (http://www.mssqltips.com/sqlservertip/3466/cascaded-parameters-in-sql-server-reporting-services/).

basically, you'll add new parameters not use them filter unless reports 7 or 8 selected. unfortunately, there's not method know of disable parameter based on parameter selection.

i'm guessing expression report parameter returns value of 1 - 8 based on report selected. example should report 6:

=iif(instr(join(parameters!report.value, ","), 6) > 0, false, true)

the filter use new inventory_item parameter like:

=iif(instr(join(parameters!report.value, ","), "7") > 0  or  instr(join(parameters!report.value, ","), "8") > 0,   iif(parameters!inventory_item.value = fields!inventory_item.value, true, false), true)

this restrict data inventory_item if report 7 or 8.
