SSRS passing multiple string parameter to another report

Question

I have read some other posts about this problem, but couldn't get it to work unfortunately.

I have 2 SSRS reports. The first report take a multiple string parameters, runs a select query, and present some rows. Then I have a "Go to Report" Action that pass the values to a sub report and run an update query to update the rows.

When passing the multiple value parameter to another report I used =join(Parameters.ponum,Value,".") but the sub report only recognize the parameter as 1 value. The parameter on the sub report has set to allow multiple value already.

The type of values I want to pass is like 'a-01', 'b-02', 'd01-293'. However, when passed to another report the parameter becomes a-01, b-02, d01-293

I tried to pass with = "'" + join(Parameters.ponum,Value,"'.'") + "'" but still fails.

Is there any other ways I can do this?

Thanks

If your subreport's parameter is multi-value like your main report parameter then in the subreport properties all you do is set the parameter value to your main report's parameter.

So if we have MainReport with a parameter called PoNum and it is multi-value. Then we have mySubReport with a parameter of subPONums for example then in the subreport placeholder in the main report, set the parameter value to [@PoNum]

The entire parameter object will be passed to the subreport.
