Appel à l'aide BAPI_PO_CREATE SAP.Net Connector 3.0

Question

Je suis en train de créer ordre d'achat dans SAP de mon application .NET en utilisant SAP.net Connector 3.0 Cependant, je reçois le message suivant d'erreur dans le paramètre RETOUR

ME159: Fonction modules invoqués dans la mauvaise séquence.

J'utilise ci-dessous le code:

// helper method to get destination from destination configuration 
var dest = RfcConfigurationHelper.GetDestination(); 

RfcSessionManager.BeginContext(dest); 

IRfcFunction rfcFunction = dest.Repository.CreateFunction("BAPI_PO_CREATE"); 

IRfcFunction transaction = dest.Repository.CreateFunction("BAPI_TRANSACTION_COMMIT"); 
transaction.SetValue("WAIT","X"); 

IRfcStructure header = rfcFunction["PO_HEADER"].GetStructure(); 
header.SetValue("DOC_TYPE", "NB"); 
header.SetValue("PURCH_ORG", "0001"); 
header.SetValue("PUR_GROUP", "001"); 
header.SetValue("DOC_DATE", DateTime.Now.ToString("yyyy-MM-dd")); 
header.SetValue("VENDOR", "V544100170"); 

IRfcTable items = rfcFunction["PO_ITEMS"].GetTable(); 
IRfcStructure item = items.Metadata.LineType.CreateStructure(); 
item.SetValue("PO_ITEM", "1"); 
item.SetValue("PUR_MAT", "TEST_MAT"); 
item.SetValue("PLANT", "0001"); 

IRfcTable shedules = rfcFunction["PO_ITEM_SCHEDULES"].GetTable(); 
IRfcStructure shedule = shedules.Metadata.LineType.CreateStructure(); 
shedule.SetValue("PO_ITEM", "1"); 
shedule.SetValue("DELIV_DATE", DateTime.Now.AddDays(7).ToString("yyyy-MM-dd")); 
shedule.SetValue("QUANTITY", 10); 

rfcFunction.Invoke(dest); 

transaction.Invoke(dest); 

IRfcTable returns = rfcFunction["RETURN"].GetTable(); 
RfcSessionManager.EndContext(dest); 

S'il vous plaît aider. Merci

Enfin, j'ai compris ce qui me manquait. C'était une erreur stupide. Ci-dessous le code édité

// helper method to get destination from destination configuration 
var dest = RfcConfigurationHelper.GetDestination(); 

RfcSessionManager.BeginContext(dest); 

IRfcFunction rfcFunction = dest.Repository.CreateFunction("BAPI_PO_CREATE"); 

IRfcFunction transaction = dest.Repository.CreateFunction("BAPI_TRANSACTION_COMMIT"); 
transaction.SetValue("WAIT","X"); 

IRfcStructure header = rfcFunction["PO_HEADER"].GetStructure(); 
header.SetValue("DOC_TYPE", "NB"); 
header.SetValue("PURCH_ORG", "0001"); 
header.SetValue("PUR_GROUP", "001"); 
header.SetValue("DOC_DATE", DateTime.Now.ToString("yyyy-MM-dd")); 
header.SetValue("VENDOR", "V544100170"); 

IRfcTable items = rfcFunction["PO_ITEMS"].GetTable(); 
IRfcStructure item = items.Metadata.LineType.CreateStructure(); 
item.SetValue("PO_ITEM", "1"); 
item.SetValue("PUR_MAT", "TEST_MAT"); 
item.SetValue("PLANT", "0001"); 

// this was missing as I haven't added the row to the table 
items.Insert(item); 

IRfcTable schedules = rfcFunction["PO_ITEM_SCHEDULES"].GetTable(); 
IRfcStructure schedule = shedules.Metadata.LineType.CreateStructure(); 
schedule.SetValue("PO_ITEM", "1"); 
schedule.SetValue("DELIV_DATE", DateTime.Now.AddDays(7).ToString("yyyy-MM-dd")); 
schedule.SetValue("QUANTITY", 10); 

// this was missing as I haven't added the row to the table 
schedules.Insert(schedule); 

rfcFunction.Invoke(dest); 

transaction.Invoke(dest); 

IRfcTable returns = rfcFunction["RETURN"].GetTable(); 
RfcSessionManager.EndContext(dest);
