Generating duplicate IDs when creating requirements tracking links

I created a tracking link for the SwRS ID and SwAD ID.

Then I created a tracking link with the same IDs again.

In my opinion, tracking links should not be created with the same ID.

However, the links are created.

Note: “ Warning: Link to DCBC_SWAD_ID_Req.slreqx:36 already exists”

Is there any way to prevent this?

Hi @JinWook Park,

The link created by 'slreq.createLink' is for a requirement having a description. Multiple requirements can be satisfied by a single destination file for a given source file, Hence 'slreq.createLink' creates a link but with a new SID.

You want to prevent multiple links between same source and destination files.

To prevent this behaviour you can check for if a link already exists between a source and destination file and create a link if it is not present. Here is a simple MATLAB function for the same.

function linkExist = checkIfLinkExists(src, dest)
inwardLinks = slreq.inLinks(dest);
linkExist = 0;
for i=1:size(inwardLinks,2)
    
    if strcmp(source(inwardLinks(i)).artifact, which(src))
        linkExist = 1;
        return
    end
end
end

Please go through this official MATLAB documentation of 'slreq.inLinks' to learn more.

doc slreq.inLinks

You can also access the workdlow of creating and link requirements from this documention.

Hello, @Kanishk

Thank you for answering my question.

I'll try with what you told me.

Thanks, I solved it well with your help.

function linkExist = checkIfLinkExists(srcReq, dest, srcid, destid)

inwardLinks = slreq.inLinks(dest);

linkExist = 0;

for i=1:size(inwardLinks,2)

if strcmp(destination(inwardLinks(i)).id,destid)

GetSrcReq = find(srcReq,'Type','Requirement','SID',source(inwardLinks(i)).id)

if strcmp(GetSrcReq.Id,srcid)

linkExist = 1;

return

end

end

end

end

Glad it helped!!
