Linking HR Documents

Hi All

We have a requirement from the client to store employee documets such as resume, certificates in the PA30 / PA20 trasactions

According to my view, we can go for creating a customized object link, so that we can attach the above documents in the content server and link then to theses trasactions PA20/ PA30.

In some of the pevious threads, I read that we should use the Archive link functionality and sap DMS will not be suitable

Kindly let me know the drawbacks when i go for cusomization in SAP DMS.

Thanks and Regards
