How to extract SAP ERP data for a particular year

Question

I am trying to extract BSEG table data from SAP ERP system. I want to set a filter on field GJAHR for year 2018 so that data for that particular year will be extracted. Below is the code snippet:

if(fields != null){
   JCoTable table = function.getTableParameterList().getTable("FIELDS");
   for (String field : fields) {
    table.appendRow();
    table.setValue("FIELDNAME", field);
    }
 }

Answer 1

If you use the function module RFC_READ_TABLE, there is a table parameter called OPTIONS, which has one column named TEXT. Here the condition for GJAHR = 2018:

JCoTable options = function.getTableParameterList().getTable("OPTIONS");
options.appendRow();
options.setValue("TEXT", "GJAHR EQ 2018");
