[Work Manager 6.5.1] Issue with extending Part class

[Former Member]

Hi SAP Experts,

I was having an issue with adding a field ZRecipient (WEMPF) which has been already existed on backend to Java class ZPart (extension of standard Part java class).

The error happened at the getBAPIConstant(Class<?> cls, String key) method of standard object Ex12nManager when the hp object is null trying to call getProperties method. Could you have a look and advise why my ZClass which looks very simple was not detected in Ex12nManager. Any response would be highly appreciated. Below is my code and the log file

My code:

public class ZPart extends Part
{
  public String ZRecipient = "";
   
  public ZPart() {}
  
  public ZPart(User user) throws Exception  {	 
          this._user = user;
	  this._compManager = ((WorkorderComponentManager)this._user.getComponentManager(COMPONENT_MANAGER_CLASS_NAME));	  
  }
  
  public ZPart(JCO.Table tbl, JCO.Table longTextTbl, Workorder wo)
		    throws Exception {
	  
	  this(wo.getUser());
	  setProperties(tbl, wo);
	  setNotes(longTextTbl);
          setZWEMPF(tbl.getString("WEMPF")); 
	}
 public void setProperties(JCO.Table tbl, Workorder wo) throws Exception{ 
	 super.setProperties(tbl,wo); 	 
 }
 
 public String getZWEMPF() {
	 //Recipient
    return this.ZRecipient;
  }  
  public void setZWEMPF(String ZWEMPF) {
    this.ZRecipient = ZWEMPF;
  } 
}

Hi,

It looks like there is no value returned. Did you verify the BAPI has values returned?
