Mapping logic for target field

Hi All,

From sender field i am getting 3 fixed values. based on that it will create 3 target nodes, up to this it's fine. from the same sender field i have mapped one more target field. for that the conditions is like below

for example, the 3 values like a,b,c, d from sender field(MAKN)

(1) if MAKN equals to a then it will pass the value from other field which we have mapped(the value will come form another field)

(2) if MAKN equals to b then it will pass the value from other field which we have mapped(the value will come form another field)

for both above conditions i have used if then else conditions it's working fine.

(3) in this condition when MAKN is equal to C then the target field should not create under the node.

For example the below address information contains name,street and address.

For the 3rd condition how i need to populate only name and number??

address information(node)

name

street

number
