Code to Avoid Looping while calling User Exit

Resolving The Problem

In Yantra, sometimes through certain events or user exits, there is possibility of looping. this has to be avoided specifically through adding a particular piece of code in the java class file.

For example with DoOrderPricing user exit implemented for createOrder.0005 . internally, changeOrder is being called, which in turn calls DoOrderPricing user exit again.

the sample code to be added is given below:

YCPInternalContext ycp = (YCPInternalContext)env;
Map userObj = (Map)ycp.getUserObject();
if(userObj == null)
{
userObj = new HashMap();
userObj.put("CALLED","Y");
ycp.setUserObject(userObj);
}
else{
String sUserExit = (String)userObj.get("CALLED");
System.out.println("UserExit:"+sUserExit+":User:"+userObj);
if("Y".equals(sUserExit))
return ;
else
userObj.put("CALLED","Y");

}

//calling changeOrder API
YIFApi chOrdApi= YIFClientFactory.getInstance().getApi();
chOrdApi.changeOrder (env, makeXML(inXML).getDocument());
