SSRS Report DP Class

Hi,

Can someone tell me if i have to add item number field from ProdBom table to ProdJobCard report but with these specifications, Item number per operation per job.

Let say if one production order PO-0011  has 

operation num- 10, 20 ,30 ,40

           JobId

 10 -  AB-0011

 10 -  AB-0012

 20 - AC-0013

 30 - AC-0015 

40 - AD-0056 

I want my report to print all item number respect to per operation, per  job id on the bottom of the page.

Please give me some suggestion. Thanks
