1. I have developed a main report which contains item inventory details ( qty on hand, replinishment parameters).

The Sub-report contains open purchase orders for items and pending delivery quantities('pendqty'). I wish to display PendQty against each of the items in the main. I have made attempts to link the subreport to the main, using 'Item' as the link field. Due to some reason the linking doesnt seem to be working right. Some of the help material i have read, indicate that the system generated parameter fields are to be used for linking , while others suggest that user defined parameter fields need to be created for the linkage.

Whats the correct method?

 

2. An alternate solution was to used the SharedVariable concept. I have defined Shared numbervar in both reports thru the formula definition. the subreport has been placed in a header before the variable declaration in the main. The formula field PendQty ( also the shared variable) placed in the main shows "0".

What seems to be the  issue in the way the concept has been used? 

 

3. Which of the above is a better option for linking the 2 reports?

 

Thx
