Logistic regression with BY statement ERROR message - sas

Question

I'm currently working on a SAS program that processes 50 logistic regression for 50 different samples. I previously had help on this thread (How to loop a logistic regression n number of times?), people advised me to use a BY statement to avoid looping this process n times. Works really well but I get this ERROR MESSAGE:
ERROR: No valid observations due either to missing values in the response, explanatory, frequency, or weight variable, or to
nonpositive frequency or weight values.
NOTE: The above message was for the following BY group:
Sample Replicate Number=.
You'll find my code below, if any of you have an idea of where does it come from, I'm open to anything, thank you in advance!

Probably from this:
DATA WORK.TMP0TempTableAddtnlPredictData;
SET WORK.APPEND_TABLE(IN=__ORIG) WORK.BASE_PREDICT_2;
__FLAG=__ORIG;
__DEP=TOP_CREDIT_HABITAT_2017;
if not __FLAG then TOP_CREDIT_HABITAT_2017=.;
RUN;
You're appending a dataset that does not have a replicate number on it here. I'm not really sure I follow what this dataset is - are you intending this to be added to each replicate perhaps? Then you might do something like this (untested):
DATA WORK.TMP0TempTableAddtnlPredictData;
do _n_ = 1 by 1 until (eof);
SET WORK.APPEND_TABLE(IN=__ORIG) end=eof;
output;
end;
do replicate = 1 to 5;
do n_predict = 1 to nobs_predict;
set WORK.BASE_PREDICT_2 nobs=nobs_predict point=n_predict;
__FLAG=__ORIG;
__DEP=TOP_CREDIT_HABITAT_2017;
if not __FLAG then TOP_CREDIT_HABITAT_2017=.;
output;
end;
end;
stop;
RUN;
This is the complicated way to get 5 copies of that, one for each replicate. But I'm not sure that's actually what you want - does it even have all of the variables you need? Are you sure you didn't mean to MERGE instead of SET?
Separately, I don't understand why you use the SQL step to append the two samples. I'd either do that in the same data step here or I'd use PROC APPEND, both would be faster than the SQL union and then immediately appending more to the dataset.
