Interoperability Event Interface Calls Sample Code

These steps and the accompanying example code illustrate how to create a single event:

1. Design the data structure for the real-time event.

   typedef struct tagDSD55RTTEST 
      { 
      char    szOrderCo[6]; 
      char    szBusinessUnit[13]; 
      char    szOrderType[3]; 
      MATH_NUMERIC   mnOrderNo; 
      MATH_NUMERIC   mnLineNo; 
      JDEDATE     jdRequestDate; 
      char    szItemNo[27]; 
      char    szDescription1[31]; 
      MATH_NUMERIC   mnQtyOrdered;
      MATH_NUMERIC   mnUnitPrice; 
      MATH_NUMERIC   mnUnitCost;
      char    szUserID[11];
      } DSD55RTTEST, *LPDSD55RTTEST;
   

2. Define the data structure object in the business function header file.

3. Modify the business function source to call jdeIEO_CreateSingleEvent.

   JDEBFRTN(ID) JDEBFWINAPI RealTimeEventsTest (LPBHVRCOM lpBhvrCom, 
   LPVOID lpVoid, LPDSD55REALTIME lpDS)
   {
   /* Define Data Structure Object */
   DSD55RTTEST  zRTTest   = {0}; 
      IEO_EVENT_RETURN  eEventReturn = eEventCallSuccess;
   
   /*Populate required members */
   
   /* Now call the API */ 
      eEventReturn = jdeIEO_CreateSingleEvent { lpBhvrCom,   
         "RealTimeEventsTest",    
         "JDERTOUT",    
         "SalesOrder",  
         "D55RTTEST",   
      &zRTTest,   
      sizeof(zRTTest),  
      0};
   
   /* Error in jdeFeedCallObjectEvent is not a critical error 
   and should only be treated as a warning */
      if( eEventReturn != eEventCallSuccess )
   { 
      /* LOG the Warning and return */ 
      return ER_WARNING;
      }
   

This sample code illustrates how to create an aggregate event:

DSD55RTTEST zD55TEST01 = {0};
DSD55RTTEST zD55TEST02 = {0};
DSD55RTTEST zD55TEST03 = {0};
IEO_EVENT_RETURN eEventReturn = eEventCallSuccess;
IEO_EVENT_ID szEventID;

szEventID = jdeIEO_EventInit (lpBhvrCom, eEventAggregate, "MyFunction1",
 "JDESOOUT", "EventScope1", 0, &eEventReturn);
eEventReturn = jdeIEO_EventAdd (lpBhvrCom, szEventID, "MyFunction2", NULL,
 "D55TEST01", &zD55TEST01, sizeof(zD55TEST01),0);
eEventReturn = jdeIEO_EventAdd (lpBhvrCom, szEventID, "MyFunction3", NULL,
 "D55TEST02", &zD55TEST02, sizeof(zD55TEST02),0);
eEventReturn = jdeIEO_EventAdd (lpBhvrCom, szEventID, "MyFunction3", NULL,
 "D55TEST03", &zD55TEST03, sizeof(zD55TEST03),0);
eEventReturn = jdeIEO_EventFinalize (lpBhvrCom, szEventID,"MyFunction4",0);

This sample code illustrates how to create a composite event:

IEO_EVENT_RETURN    eEventReturn    = 0;
    IEO_EVENT_ID szEventID;


   eEventReturn = eEventCallSuccess;
   szEventID = jdeIEO_EventInit (lpBhvrCom, eEventComposite, "MyFunction1",
 "JDESOOUT","EventScope1",0,&eEventReturn,0);
   eEventReturn = jdeIEO_EventAdd ( lpBhvrCom, szEventID, "MyFunction2",
 "SODOCBEGIN", "D55TEST01", &zD55TEST01, sizeof(zD55TEST01),0);
   eEventReturn = jdeIEO_EventAdd ( lpBhvrCom, szEventID, "MyFunction3",
 "SOITEMADD", "EventScope3", "D55TEST02", &zD55TEST02, sizeof(zD55TEST02),0);
   eEventReturn = jdeIEO_EventFinalize (lpBhvrCom, szEventID, "MyFunction4",0);

Errors that are returned by the system calls might not be critical enough to stop the business process. The system flags non-critical errors as warnings and logs them in the log file.
