Proc report: Print repeated column values only in one row

[juju_p]

Hello,

I would like to ask about a specific problem, I am new to SAS , working on an existing code and I am facing some issues to update it.

I have the following data printed on screen and I would like that for each Timepoint, whenever the combination of 'Lesion Type', Total Sum', 'Lesion evaluation' and  'Overall evaluation' is the same on multiple rows, I would like to show it only once.

So, for Subject 'A' the lines with the arrow should be listed one after each other. the values in purple should be printed and the values in yellow should not be printed because they are repeated.

Below are the existing code to create the dataset and also to create the report

Create Dataset

data lesrt3;
set lesrt2;
by subjid RECISTNR timept ord;
if first.ord then do;
lestype1=lestype;
eval1=eval;
TLSLDd=put(TLSLD, 9.0);
end;
else do;
lestype1='';
eval='';
TLSLDd='';
end;
if lestype='Non-Target Lesion' then tlsldd='';
if TIMEP = 99 then TIMEPT_ = compbl('Other follow-up: Week '|| compress(put(TIMEPTW,3.)));
else timept_=timept;

CTDat = CATS(DDCT1,'$',DDCT2,'$',DDCT3);
MRIDat = CATS (DDMRI1,'$',DDMRI2,'$',DDMRI3);
XRDat = CATS (DDXR1,'$',DDXR2,'$',DDXR3);
PETDAT = CATS (DDPET1,'$',DDPET2,'$',DDPET3);
OTHDAT = CATS (DDOTH1,'$',DDOTH2,'$',DDOTH3);
if LESTEC =1 then RTADAT = CTDat;
else if LESTEC =2 then RTADAT = MRIDat;
else if LESTEC =3 then RTADAT = XRDat;
else if LESTEC =4 then RTADAT = PETDAT;
else if LESTEC =5 then RTADAT = OTHDAT;

if lestype ='Non-Target Lesion' then Leseval=evantlt;
if lestype ='Target Lesion' then Leseval=evatlt;
leseval_all= overevt;
run;

Print report

Try applying PROC SORT before doing your PROC REPORT.  PROC SORT is great for eliminating duplicate rows.  Here is generalized code based of the report you provided, fill in actual table and column names.  Be careful and name a new output table with OUT= so your original table is not over written.

proc sort data=source_table out=new_table nodupkey dupout=table_with_duplicates;
by lesiontype timepoint totalsum dateofexam lesioneval overalleval;
run;
