CDS associations - please help

965 Views

What is the purpose of the new 1: addition before a filter condition?

For illustration purposes, i've created a 1 to many association between Articles and Units of Measure. (Tables MARA & MARM). Then, I created another view to 'consume' the association. No problem, but I get the following warning: Association uoms can influence the cardinality of the resulting set. (see exclamation marks in yellow triangles):

OK, fix that using the 1: addition, and the warning goes away:

My expectation now is a 1 to 1 association between Article and Units of Measure, but the result set is still 1 to many. What then does the 1: addition mean?
