I have this macro

%macro run_cas_ma;

proc cas;
/* Ensure that the session is set correctly */
session %sysfunc(getlsessref(&dataset_lib));

/* Load the necessary action set */
loadactionset %sysfunc(quote(timeData));

action runTimeCode /
table={
caslib=%sysfunc(quote(%sysfunc(getlcaslib(&dataset_lib))))%str(,)
name=%sysfunc(quote(&dataset_name))
} /* Table definition comes first */

objOut={

table={
caslib=%sysfunc(quote(%sysfunc(getlcaslib(_tmpcas_))))%str(,)
name=%qsysfunc(quote(outStatTemp)) %str(,)
replace=%sysfunc(quote(true))
}%str(,)
objRef=%str('outStat')
}
}

/* Conditionally add forecast output if plotForecastViya is set to 1 */
%if &plotForecastViya = 1 %then %do;
%str(,)

%end;

rc = mySpec.AddMAPoly(ma);
rc = mySpec.SetOption("noint",1);
rc = mySpec.SetOption("method","CLS");
rc = mySpec.close();

rc = myModel.SetY(&dependVariable);
rc = myModel.SetOption('lead', &forecastPeriods);
rc = myModel.SetOption("alpha",0.05);
rc = myModel.Run();

%if &plotForecastViya = 1 %then %do;

Use this little icon :

to paste your code like it should be:

%macro run_cas_ma;
libname _tmpcas_ cas caslib="CASUSER";

proc cas;
/* Ensure that the session is set correctly */
session %sysfunc(getlsessref(&dataset_lib));

/* Load the necessary action set */
loadactionset %sysfunc(quote(timeData));

action runTimeCode /
table={
caslib=%sysfunc(quote(%sysfunc(getlcaslib(&dataset_lib))))%str(,)
name=%sysfunc(quote(&dataset_name))
} /* Table definition comes first */

objOut={
{
table={
caslib=%sysfunc(quote(%sysfunc(getlcaslib(_tmpcas_))))%str(,)
name=%qsysfunc(quote(outStatTemp)) %str(,)
replace=%sysfunc(quote(true))
}%str(,)
objRef=%str('outStat')
}
}

/* Conditionally add forecast output if plotForecastViya is set to 1 */
%if &plotForecastViya = 1 %then %do;
%str(,)
{
table={
caslib=%sysfunc(quote(%sysfunc(getlcaslib(_tmpcas_))))%str(,)
name=%sysfunc(quote(outFcastTemp)) %str(,)
replace=%sysfunc(quote(true))
}%str(,)
objRef=%str('outFcast')
}
%end;

seasonality=12
timeId={name=%str('date') %str(,) FORMAT=%sysfunc(quote(_DATA_))}
interval="Month"
nlFormat=true
series={'sale'}
require={{pkg='TSM'}}
code=%str(%')
declare object myModel(TSM);
declare object mySpec(ARIMASpec);
rc = mySpec.Open();

/* Loop to assign values to ma[&i.] */
%do i=1 %to &map.;
ma[&i.] = &i.;
%end;
rc = mySpec.AddMAPoly(ma);
rc = mySpec.SetOption("noint",1);
rc = mySpec.SetOption("method","CLS");
rc = mySpec.close();

/* Initialize the model */
rc = myModel.Initialize(mySpec);
rc = myModel.SetY(&dependVariable);
rc = myModel.SetOption('lead', &forecastPeriods);
rc = myModel.SetOption("alpha",0.05);
rc = myModel.Run();

/* Collect forecast if plotForecastViya is set to 1 */
%if &plotForecastViya = 1 %then %do;
declare object outFcast(TSMFor);
rc = outFcast.Collect(myModel);
%end;

declare object outStat(TSMSTAT);
rc = outStat.Collect(myModel);
%str(%');
run;
%mend run_cas_ma;

%run_cas_ma

First of all: writing a macro without parameters is bad programming practice.

Second thing what are:

timeData, outFcastTemp are those mcarovariables ? or constant texts ?

Where the &map. macrovariabel comes from?

where is the definition of array "ma", that one used here:

%do i=1 %to &map.;
ma[&i.] = &i.;
%end;

Mprint in the text you pasted comes from macro: __CODE, where is that macro defined?

Assigning TRUE/FALSE values to option:

replace=%sysfunc(quote(true))

I think should be like this:

replace=1

replace=True

(see example: https://documentation.sas.com/doc/en/pgmsascdc/9.4_3.5/caspg/p1668p6hhivls3n11q05kk6h1zgj.htm)

Single-quotes embedded improperly in "code":

Etc., etc., etc.

"NOTE: The quoted string currently being processed has become more than 262 bytes long. You might have unbalanced quotation marks."

If you can't find the problem in the code, try to strip down the macro until it works, and than add code part by part until you find the problem.
