Custom field data is lost or not available after any action

Question

I added a custom field on ERP_H component and I made this field available through getter methods. I brought this field in to header view and the field looks ok but after I enter the data in that field, the value enter doesn't get retained. I saw the setter method and the data is set correctly. After any action like enter or save, data is lost or the value is not available, any clue?
below are the details:
1) We have created an append structure to CRMST_ADMINH_ERPIL and activated the getter and setter methods, I tried with AET tool too(ofcourse the Zfield are not available withe field names we need).
2) Data binding is happening in the context create note.
    model = owner->create_model(
        class_name     = 'ZL_ERP_H_HEADERDETAIL_CN03'
        model_id       = 'ERPAdminH' ).                     "#EC NOTEXT
    ERPAdminH ?= model.
    CLEAR model.
bind Context Node to controller to my enhaced context.
    owner->do_context_node_binding(
    iv_controller_type = CL_BSP_WD_CONTROLLER=>CO_TYPE_COMPONENT
    iv_target_node_name = 'ERPADMINH'
    iv_node_2_bind = ERPADMINH  ).
3) In get_p_xxx field is changed to check box
4) In Get_I_XXX method rv_diabled is changed = 'FALSE'.
5) In set property the value is set correctly.
    IF <nval> <> <oval>.
      current->set_property(
                      iv_attr_name = 'ZFREEF' "#EC NOTEXT
                      iv_value     = <nval> ).
      clear dref.
      dref = current->get_property( 'ZFREEF' ). "data is retreived correctly
    ENDIF.
6) When I check the get_property right afer the set_property the attribute is empty.
7) when I try to check the value in getter method, the value is empty.
Any help is appreciated.

Hi Sumit,
At first I tried to create the fields using AET tool. I was successfully able to add field in the model but when I did different issues came with it.
1) I was still not able to hold my data in custom additional fields added through AET tool. So no big difference between AET addition and append structure.
2) In ERP order system is going to call the ERP system through RFC in which the field name should be same as what you send from CRM. It doesn't have a option of mapping intermediately like BDOC structure or something . It calls the LORD API's and post the data. There are bunch of LORD function modules maintained in SAP.
3) to call the function module I have to maintain the same field names in my ERPAdminH structure. So I have no choice but add append structure manually with SAP ECC field name.
4) to your question regarding set property, the data is properly assigned to BOL object and very nex line t I tried to access it and it is there. So that confirmed that I was able to update the BOL structure.
Any suggestion would be appreciated.
