Making standard fields non editable

[Former Member]

Hi,

My requirement is to make few standard fields(eg.Supplier field in item source of supply in Shopping cart)as non editable depending upon the role of logged in user.I need to know whether should we need to enhance the WDDOMODIFYVIEW( ) method of the respective web dynpro component to acheive this or any other approach for this.

Thanks and Regards,

Rohani,

Go to SPRO->SAP SRM->Cross App. basic setting -> Extension & field control -> Config. Field control -> Field control on Item Level.

Define you own Class/method. You can read the user roles and enable/Disable the field.

Thanks.

Hi Surender,

Thanks for your reply.I have a doubt like how will we know the structure of that standard field.If i check my WD component,it belongs to /SAPSRM/S_CLL_WD_SUPPLIER-PARTNER.But in the customising table for metadata,if I search for PARTNER*,it is giving only this entry.

/SAPSRM/S_PDO_MDF_BO_SC_IT 0040 PARTNER_PROD BUS2121 06 BBP_PARTNER_PROD ITM FLD

Can you please help me on this?

Thanks and Regards,

Rohani, Yes It is not available in the Item Control config.

You can implement BADI WD_BADI_DOMODIFYVIEW to control the field in different View.

Sample Code, This might help you.

DATA: lr_uielementTYPE REF TO cl_wd_uielement.

If view->name = 'V_DODC_SC_I_SOS'

lr_uielement ?= view->get_element( 'FIXED_SUPPLIER ).

lr_uielement->set_enabled( lv_enable ).

lr_uielement->set_visible( '01' ).

endif.

Hi Surender,

I need a clarification.Can't I do my implementation in post-exit method of wddomodifyview()?I tried doing and when I call the BAPI to get the user details,I am getting the dump.My issue is how to get the roles of logged in user in WDDOMODIFYVIEW() method.

Thanks and Regards,

You can do it. But why are you getting a dump due to BAPI that you have used?

Hi Surendar,

The error was due to parameter passing.I have corrected the error.The "Assign Supplier" button enabled property is always checked.Also the visible property is bound to the attribute "V_DODC_SC_I_SOS.M_AS_FIXED_SUPPLIER.ASSIGN_FIXED_SUPPL_ITM".When I try to change this value in my postexit,it is giving me an error that the boolean value "ASSIGN_FIXED_SUPPL_ITM" cannot be changed.Also my requirement is to disable the Button(not making it disppear).Could you please tell mehow can i acheive this?

I am not sure why you are not going for the standard method of using authorization object, which is specially designed only for this purpose..

by the way - i enhanced the view V_DODC_SC_I_SOS in your SoS WD component and i dint find any dump..

are you sure you are using post exit not a pre-exit!!!

DATA: ret2 type table of bapiret2.
CALL FUNCTION 'BAPI_USER_GET_DETAIL'
  EXPORTING
    username             = sy-uname
  tables
    return               = ret2.

  DATA :wd_por_en TYPE REF TO cl_wd_input_field.
  wd_por_en ?= view->get_element('FIXED_SUPPLIER').
  CALL METHOD wd_por_en->set_enabled
    EXPORTING
      value = abap_false.

dint dump..

and this is the code to disable the button

DATA: wd_button type ref to CL_WD_BUTTON.
wd_button ?= view->get_element('ASSIGN_FIXED_SUPPL').
  CALL METHOD wd_button->set_enabled
    EXPORTING
      value = abap_false.

Hi Soumya,

Thank you very much.It really helped me to solve my problem.I have a doubt whether it is a good practice to call BAPI from WDDOMODIFYVIEW() METHOD.Could you pls clarify me

Thanks,

You can call the BAPI from a WD Method. It is perfectly fine. Hope you have got your issue resolved.

mate, BAPIs are good fellows. you can use them as long as you know what they are used for.
