Need web report joins to get 1 to 1 mapping between movement Request nbr and task nbr

Summary:

We are able to join multiple tables to get 1 to 1 mapping between task nbr and WMS order nbr. However we are unable to find the joins to map 1 to 1 between movement request number and task number. Please provide the joining criteria if available?

Content (please ensure you mask any confidential information):

We need a report to tell which task number is picking against which movement request even if the same replenishment template run allocates multiple movement requests. If a single replenishment template or wave run allocates 5 movement requests with same items and generates 30 tasks. How can we know which task belongs to which movement Request?
