Adding a new variable but the labels of the previous datasets are not kept. how to solve that issue

[alepage]

Hello,

I adding the variable ORGNL_SAS_DS_ROW_NBR and it works fine. But if we make a proc compare, we see that in the original dataset the lable are present and in the new dataset all the label seems to be blank.  How to solve that issue ?

libname  BANDE1 spde '/.../Temp/Alain/test/Classic/gc/auto';
libname  BANDE2 spde '/.../Temp/Alain/test/Classic/gc/habi';
libname  BANDE3 spde '/.../Temp/Alain/test/Classic/gc/entr';

libname  BANDE4 spde '/.../Temp/Alain/test/Classic/gc2/auto';
libname  BANDE5 spde '/.../Temp/Alain/test/Classic/gc2/habi';
libname  BANDE6 spde '/.../Temp/Alain/test/Classic/gc2/entr';

%let co=gc;
%let moisc=feb;
%let year=2025;

Data BANDE4.&CO._AUTO_PRM&MOISC.&YEAR. ;
ORGNL_SAS_DS_ROW_NBR=_N_;
set BANDE1.&CO._AUTO_PRM&MOISC.&YEAR. ;
run;

/****** Bande2 for Property *****/

Data BANDE5.&CO._PROP_PRM&MOISC.&YEAR. ;
ORGNL_SAS_DS_ROW_NBR=_N_;
set BANDE2.&CO._PROP_PRM&MOISC.&YEAR. ;
run;

/****** Bande3 for Enterprise *****/
data BANDE6.&CO._CNA_PRM&MOISC.&YEAR. ;
ORGNL_SAS_DS_ROW_NBR=_N_;
set BANDE3.&CO._CNA_PRM&MOISC.&YEAR. ;
run;

/****** The proc compare steps *********/

proc compare base=bande1.&CO._AUTO_PRM&MOISC.&YEAR. compare=BANDE4.&CO._AUTO_PRM&MOISC.&YEAR.

run;
proc compare base=bande2.&CO._prop_PRM&MOISC.&YEAR. compare=BANDE5.&CO._prop_PRM&MOISC.&YEAR. 
listvar ;
run;
proc compare base=bande3.&CO._CNA_PRM&MOISC.&YEAR.  compare=BANDE6.&CO._CNA_PRM&MOISC.&YEAR.  
listvar ;

Looks like you turned off the LABEL option.

Example:

data class;
  set sashelp.class;
  label name='Student Name';
run;
options nolabel;
data class2; set class; run;
options label;
data class3; set class; run;
proc compare data=class compare=class2;
run;
proc compare data=class compare=class3;
run;
