Lock Error on SAS Dataset Library when executing multiple PROC import simultaneously

dennis_oz — Tue, 12 May 2020 09:23:31 GMT

Hi , can someone please help me with this error. Thanks,

Error I am getting:

ERROR: Entry lock is not available for IMPORT_STRATEGICFILE.MACRO in catalog WORK.SASMAC1, lock held by IOM ROOT COMP ENV.

ERROR: The macro IMPORT_STRATEGICFILE could not be saved in the WORK.SASMACR catalog. A previous version of the macro was in use

and could not be replaced.

ERROR: The SAS Macro Facility has encountered an I/O error. Canceling submitted statements.

Code that I am executing

%Macro Import_StrategicFile(rtcf_file,output_file);

%let path1 = xxxx;
%let reporttab = Records;

proc import
datafile="&path1\&rtcf_file." out=My_lib.&output_file. dbms=xlsx replace;
/* datafile="&path1\&rtcf_file." out=work.&output_file. dbms=xlsx replace;*/
getnames=yes;
sheet="&reporttab.";
run;
/* to move the fimported file to archive location*/
%sysexec move "&path1\&rtcf_file." "&path1\Archive";

%Mend Import_StrategicFile;

data _null_;
set wash_file;
call symput ('file_date',file_date);
select (actual_file_name);
when ('AAAA') rc=dosubl('%Import_StrategicFile(AAAA_&file_date.,HI_AAAA)'); /* doing pro import to same library*/
when ('BBBB') rc=dosubl('%Import_StrategicFile(BBBB_&file_date.,BBBB)'); /* doing pro import to same library*/
when ('CCCC') rc=dosubl('%Import_StrategicFile(CCCC_&file_date.,CCCC)'); /* doing pro import to same library*/
otherwise put=hi;
end;
run;

I have entered " options mprint mlogic ; "

could that be the issue . I removed that but have not been able to test the code ..

Your code as such won't work:

data _null_;
set wash_file;
call symput ('file_date',file_date); /* this is executed at data step _runtime_ */
select (actual_file_name);
when ('AAAA') rc=dosubl('%Import_StrategicFile(AAAA_&file_date.,HI_AAAA)'); /* doing pro import to same library*/
/* the reference to &file_date will not be resolved because of the single quotes */
/* but it won't work anyway, as it would be resolved at data step _compile time _*/
when ('BBBB') rc=dosubl('%Import_StrategicFile(BBBB_&file_date.,BBBB)'); /* doing pro import to same library*/
when ('CCCC') rc=dosubl('%Import_StrategicFile(CCCC_&file_date.,CCCC)'); /* doing pro import to same library*/
otherwise put=hi; /* You try to assign the value of variable hi to variable put; is this what you intended? */
end;
run;

I suggest these changes:

data _null_;
set wash_file;
select (actual_file_name);
  when ('AAAA') rc=dosubl('%Import_StrategicFile(AAAA_' !! strip(file_date) !! ',HI_AAAA)'); /* doing pro import to same library*/
  when ('BBBB') rc=dosubl('%Import_StrategicFile(BBBB_' !! strip(file_date) !! ',BBBB)'); /* doing pro import to same library*/
  when ('CCCC') rc=dosubl('%Import_StrategicFile(CCCC_' !! strip(file_date) !! ',CCCC)'); /* doing pro import to same library*/
  otherwise put=hi; /* change as needed */
end;
run;

Hi,

I did small experiment. I've created 3 xlsx files `AAAA_X.xlsx`, `BBBB_X.xlsx`, and `CCCC_X.xlsx` in my WORK location, I also created `Archive` subfolder and I used following dataset and MyLib:

libname My_lib (work);

data wash_file;
  actual_file_name = 'AAAA'; file_date= "X.xlsx"; output;
  actual_file_name = 'BBBB'; file_date= "X.xlsx"; output;
  actual_file_name = 'CCCC'; file_date= "X.xlsx"; output;
run;

than only change i did with you code was

%let path1 = %sysfunc(pathname(work));
%let reporttab = Arkusz1;

to adjust my excels and their names

after running:

resetline;
libname My_lib (work);

data wash_file;
  actual_file_name = 'AAAA'; file_date= "X.xlsx"; output;
  actual_file_name = 'BBBB'; file_date= "X.xlsx"; output;
  actual_file_name = 'CCCC'; file_date= "X.xlsx"; output;
run;

%Macro Import_StrategicFile(rtcf_file,output_file);

%let path1 = %sysfunc(pathname(work));
%let reporttab = Arkusz1;  

proc import
datafile="&path1\&rtcf_file." out=My_lib.&output_file. dbms=xlsx replace;
/* datafile="&path1\&rtcf_file." out=work.&output_file. dbms=xlsx replace;*/
getnames=yes;
sheet="&reporttab.";
run;
/* to move the fimported file to archive location*/
%sysexec move "&path1\&rtcf_file." "&path1\Archive";


%Mend Import_StrategicFile;

data _null_;
set wash_file;
call symput ('file_date',file_date);
select (actual_file_name);
when ('AAAA') rc=dosubl('%Import_StrategicFile(AAAA_&file_date.,HI_AAAA)'); /* doing pro import to same library*/
when ('BBBB') rc=dosubl('%Import_StrategicFile(BBBB_&file_date.,BBBB)'); /* doing pro import to same library*/
when ('CCCC') rc=dosubl('%Import_StrategicFile(CCCC_&file_date.,CCCC)'); /* doing pro import to same library*/
otherwise put=hi;
end;
run;

I have nice and clear log without errors:

1) are there any other assumptions about your data we don't know?

2) your datastep has issues: `NOTE: Variable hi is uninitialized`

3) are your input data ok?

i am lost

did you mean || strip(file_date) || rather than !! strip(file_date) !!

thanks the code is working for me as well .. I don't know why it showed a lock the first time

The double exclamation signs are syntactically equivalent to the double pipe character.

But as @yabwon demonstrated, the other method will also work, but I prefer to use macro elements only when absolutely needed.
