SSRS passing data from master report to subreport

Question

I have a report MRpt which has a subreport SRpt. MRpt has 2 datasets ds1, ds2. SRpt has 1 dataset dsA. All datasets are generated by different stored procedures. I've been trying to pass the data from the master report datasets to the subreport using various suggestions here but it doesn't seem to help so far. Here is a short description of what I try to accomplish.

The MRpt has a tablix that displays some data as below (For each PartNumber in MRpt, the SRpt will display the history of credit return approval)

PartNumber| AskedPrice| AskedQuantity| ApprovedPrice| ApprovedQty
PN_1      |       2.00|            50|          1.50|          50
    InvoiceNumber| InvoicePrice| InvoiceQty| ApprovedPrice| ApproveQty
    240204       |        24.25|         70|          0.50|         50
    220203       |        25.50|       1570|          2.50|       1500

PN_3      |      50.00|            20|         27.50|          20
    InvoiceNumber| InvoicePrice| InvoiceQty| ApprovedPrice| ApproveQty
    240204       |        60.25|        100|         30.50|         70
    220201       |        50.50|       2000|         26.50|       1500
    220109       |        40.50|       1000|         20.50|       1000

I need to pass to the SRpt these values from the MRpt datasets: ds1.CustomerID, ds1.StartDate, ds1.EndDate, ds2.PartNumber.

Is it possible? If so, how do I go about to do this? Where should I place the SRpt so it will be shown as above illustration. I'm currently getting error: SubReport could not be shown. If I run the SRpt alone, it displays data correctly.

Please help.

I added some screen shots so you guys can help if I did something wrong.

This is the subreport design view

This is the subreport properties from master report

This is how I hook up the parameters

Answer 1

If you have properly set up the values you specified as parameters in your subreports then it should be no problem to send them from the master report. There should be a listing of all subreport parameters when you include a subreport and there you would hook up your params.
