I have a dataset that if it. Matchs i would need another col to be null

The data looks
Id. Type. Sch
A1. Cd. Mon tue
Ab. Store. Tue wed
S1. Cd. Wed
A5. Store. Mon


When type eq Cd i would w want sch to be null

.id Type. Sch
A1. Cd.
Ab. Store. Tue wed
S1. Cd.
A5. Store. Mon

if upcase(type)='CD' then call missing(sch);

[singhsahab · Accepted solution]

data want;
	set have;

	if upcase(type)='CD' then
		Sch='';
run;
