Transparency violation error. 'save' in 'parfor' loop

I am new to coding,

Here's the complete code:

Dset = 'visit3'; % visit3
Mpath = 'E:\OneDrive - IITRAM'; %dataset path
Lpath = 'E:\datasetttt\numom2b\polysomnography';
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
sp1 = 'MAT files';
op1 = 'edfs'; %edfs
op2 = 'annotations-events-profusion'; %xml

Ldir = struct2cell(dir([Lpath,'\',op1,'\',Dset]));
Ldir = Ldir(1,3:end)';

sp2 = strcat(Mpath,'\',sp1,'\',Dset);
if isfolder(sp2) ==0
    mkdir(sp2)
end
parfor i = 1:1903 %size(Ldir,1)  
    CSname = char(Ldir(i,1));
    [hdr, record] = edfread(CSname); % Edf2mat
    CSname = CSname(1:end-4);
    y = xml2struct([CSname,'-profusion.xml'],0);
    
    save([sp2,'\',CSname,'_rec'],'record')
    save([sp2,'\',CSname,'_info'],'hdr','y')
    
    clc
    disp(i)
    toc
end

I know this error comes cuz of the 'save' in 'parfor' loop

people have suggested that we have to define the save as a function

But i am having a hard time figuring it out

I'd be glad if someone helps

thank you.

How about you define two save functions

function mysave1(sp2,CSname,record)
save([sp2,'\',CSname,'_rec'],'record');
end

function mysave2(sp2,CSname,hdr,y)
save([sp2,'\',CSname,'_info'],'hdr','y')
end

Then just call these in your parfor loop.
