我目前使用 SAP JCO 连接到 SAP 并从 SAP 表中获取数据。我使用内部 BAPI 函数从 SAP 表中获取数据。我想知道如何从 SAP 表中获取数据的方法,只需指定表名和应从中检索数据的列。
下面是我用来通过 BAPI 函数获取数据的代码。
JCoFunction function = destination.getRepository().getFunction("BAPI_COMPANYCODE_GETLIST");
if(function == null)
throw new RuntimeException("BAPI_COMPANYCODE_GETLIST not found in SAP.");
try
{
function.execute(destination);
}
catch(AbapException e)
{
System.out.println(e.toString());
return;
}
JCoStructure returnStructure = function.getExportParameterList().getStructure("RETURN");
if (! (returnStructure.getString("TYPE").equals("")||returnStructure.getString("TYPE").equals("S")) )
{
throw new RuntimeException(returnStructure.getString("MESSAGE"));
}
JCoTable codes = function.getTableParameterList().getTable("COMPANYCODE_LIST");
final FileWriter outFile = new FileWriter("D:\\out.csv");
for (int i = 0; i < codes.getNumRows(); i++)
{
codes.setRow(i);
}
codes.firstRow();
for (int i = 0; i < codes.getNumRows(); i++, codes.nextRow())
{
function = destination.getRepository().getFunction("BAPI_COMPANYCODE_GETDETAIL");
if (function == null)
throw new RuntimeException("BAPI_COMPANYCODE_GETDETAIL not found in SAP.");
function.getImportParameterList().setValue("COMPANYCODEID", codes.getString("COMP_CODE"));
function.getExportParameterList().setActive("COMPANYCODE_ADDRESS",false);
try
{
function.execute(destination);
}
catch (AbapException e)
{
System.out.println(e.toString());
return;
}
returnStructure = function.getExportParameterList().getStructure("RETURN");
if (! (returnStructure.getString("TYPE").equals("") ||
returnStructure.getString("TYPE").equals("S") ||
returnStructure.getString("TYPE").equals("W")) )
{
throw new RuntimeException(returnStructure.getString("MESSAGE"));
}
JCoStructure detail = function.getExportParameterList().getStructure("COMPANYCODE_DETAIL");
非常感谢任何有关如何通过仅指定表名和列来访问 SAP 表的帮助。提前致谢
