Hello Experts,
I'm wondering how to take the value from a precedent raw. The lag function doesn't work.
I have joined the data.
Thank you very much for your help.

I guess you mean that values are carried over from one BY group to the next. But this can be avoided:
data want; set have; by numero code2; MT2_CORR_befor=ifn(first.code2,.,lag(MT_2_CORR)); run;
