Multi Mapping


I have a scenario where I need to use multi mapping (1:N). When we do that in mapping editor, SAP adds our message <Message> & <Message1&2>

So for e.g. our message is Mt_test1 & MT_test2 after having (1: N) it will look like











(1) I did not understood why it is done

(2) Cardinality of both Message & Message1, Messag2 is set to 1:1 by default by SAP.

I have a condition that if the data in MT_test1 comes blank , than I should not generate any message.

While putting the condition, createif, I am facing an runtime error since the Message & message1 &2 are set to 1:1 which prevent it from creating nothing..

Can you advice, how can I achieve this condition or change the cardinality of Message to 0..1
