Relation ship Map - Sales Quotation to Incoming Payments

Dear Experts,

I had an issue in the SAP Relationship Map,

From the SQ to Incoming payments (in between SQ and Incoming payments, there are some documents like AR down payment invoice/Deliver Note / AR Invoices)

When I preview the relationship Map for a particular SQ it is showing only 2 incoming payments.

For examples

SQ (2350)----> Incoming payments(203,206))

  But  there is a receipt(227), that one also based on the particular SQ. When we click the based documents (from Incoming payent 227)button form from respective documents in between SQ and RC, it is going up to that particular SQ.

What is the issue ?

Thanks

Best Regards

Gobi
