I am trying to "insert" (or) "add a row" to Purchase Requisition using standard BAPI (PurchaseRequisition.CreateFromData).
I am using JCo3. The example in JCo3 indicates that we should use table.appendRow() OR table.insertRow() methods. I am trying with table.appendRow() & table.appendRows(1). When i try to insert a row, i dont get any error and the row is not inserted.
Below is the program i am trying to execute. /** Below are the inputs required for this program to run / / Step 1 **/ String BAPI_NAME = "BAPI_REQUISITION_CREATE";
/** Step 2 **/
String query_input_column1 = "DOCUMENTY_TYPE";
String query_input_column1_value = "NB";
String query_input_column2 = "PREQ_NAME";
String query_input_column2_value = "Name";
String query_input_column3 = "ACCTASSCAT";
String query_input_column3_value = "U";
String query_input_column4 = "DELIV_DATE";
String query_input_column4_value = "20131101";
String query_input_column5 = "MATERIAL";
String query_input_column5_value = "DELL-RQ2013";
String query_input_column6 = "QUANITY";
int query_input_column6_value = 10100;
/** Step 3 **/
String targetTableUnderBAPI = "REQUISITION_ITEMS";
/** Step 4 **/
/** For the confirmation read the value from export parameter after insertion execution **/
String result_column1 = "NUMBER";
JCoDestination destination = null;
try {
destination = JCoDestinationManager.getDestination(DestinationManager.DESTINATION_NAME1);
JCoRepository repository = destination.getRepository();
JCoContext.begin(destination);
JCoFunction function = repository.getFunction(BAPI_NAME);
if(function == null)
throw new RuntimeException(BAPI_NAME + " not found in SAP.");
System.out.println("BAPI Name from function object: " + function.getName());
//function.getImportParameterList().setValue(query_input_column1, query_input_column1_value);
JCoTable table = function.getTableParameterList().getTable(targetTableUnderBAPI); //it is taken from the response value of metadata
//System.out.println("No of Columns: "+ table.getNumColumns());
System.out.println("Trying to execute append row");
table.appendRow();
table.setValue(query_input_column1,query_input_column1_value);
table.setValue(query_input_column2,query_input_column2_value);
table.setValue(query_input_column3,query_input_column3_value);
//table.setValue(query_input_column4,new java.util.Date(query_input_column4_value));
//skipped Other columns related code
try{
function.execute(destination);
}
catch(AbapException e){
System.out.println(e.toString());
return;
}
System.out.println("Let us check the result from export parameter");
String exportParamStructure = (String)function.getExportParameterList().getValue(result_column1); //getStructure(result_column1); // getValue(result_column1);
System.out.println("Resulting PR#: "+exportParamStructure);
} catch (JCoException e) {
e.printStackTrace();
}
finally
{
try {
JCoContext.end(destination);
} catch (JCoException e) {
e.printStackTrace();
}
}
I did not understand how to read the response and am trying to fetch it from exportParameters!!
Please note that my knowledge on SAP is very limited.
Waiting for an expert's response.
Thanks.
First, you should take a look at SAP JCo documentation, e.g. http://help.sap.com/saphelp_nw04/helpdata/en/6f/1bd5c6a85b11d6b28500508b5d5211/content.htm
Regarding your code:
If you don't like to fiddle with the more or less complicated and verbose JCo API, try using Hibersap which gives you a much nicer programming model when calling functions in SAP ERP: http://hibersap.org.
However, you will still need a basic understanding on how SAP function modules work technically (such as parameter types or data types) as well as on the domain specific model which lies behind them (in your case, creating a requisition). I.e. you may need to communicate with your SAP experts.
