<div>Dear Experts,</div>
<div> </div>
<div>We need to develop a multi-level approve workflow for employee leave request base on standard template WS12300111. After read through the relevant threads, I found the usual way is to enhance one more method in class CL_PT_REQ_WF_ATTRIBS to change the attribute 'status' after 1st level approval. Since workflow task dose not recognize enhancement in class, the suggested method is to create a wrapper class instead. I have no experience about wrapper class at all, and there are very limited information online, now I'm stuck at this step.</div>
<div>Does anyone have the experience with wrapper class and would like to give some advices? Thanks a lot.</div>
