We are missing 3 values as A,B,C in our process and we can have different combinations of them being missing. So we want to write in mail what all we are missing.
for e.g. sometimes only A can miss, sometimes A,B can miss. Sometimes even A,B,C can even miss.
So we want to write like
“A is missing in process”
“A and B is missing in process” like that
If anybody can help here.
