need help with something like a pivot

[Unstefan]

Hello,

Need some help with the following situation :

 - need to cumulate the amount for variable nocont

but in SAS

I try with summary but doesn't work

nocont	tip	date	amount
A	x	17-Oct-18	2.00
B	y	17-Oct-18	3.00
C	z	17-Oct-18	4.00
A	x	17-Oct-18	100.00
C	z	17-Oct-18	1234.24
C	z	17-Oct-18	34.00
B	y	17-Oct-18	279.00
D	g	17-Oct-18	45.00
E	j	17-Oct-18	38.00
F	k	17-Oct-18	339.00

Post test data in the form of a datastep.  Show what the output should be from that datastep.  Explain (with log if needed) what "doesn't work".   From what you post:

proc summary data=have;
  class nocont;
  output out=want sum()=;
run;

Should work.
