I am working with Xcode using Objective C and SUP 2.1.3 backend. I want to insert some data. For that I have used create command.

```
[createReq setCUST_ID:instBaseS.CUST_ID];  
    [createReq setCust_Name:custName.text];

    [createReq setIbase_ID:instBaseS.IBASE_ID];
    [createReq setProduct_ID:pdtID.text];
    NSLog(@"ibase id is %@",instBaseS.IBASE_ID);
    [createReq setProblem_Desc:problmDesc.text];
    [createReq setSub_Product_ID:@"MOTOR"]; 
      NSLog(@"installed bases cust id %@",instBaseS.CUST_ID);

    [createReq create];   
   // [FieldServiceCom_igate_Reshma_fieldservice_ALL_v6DB synchronize];

[createReq submitPending];

```

In the line `[createReq create];` we are getting an exception like 

```

terminate called throwing an exception(lldb) 

```

Why are we getting this exception?  
 Do we want to synchronize DB after the 'create' command?  
 If the steps above are wrong, what are correct steps to active this?.
