Add Column in the Powl list

[former_member314998]

Hi Experts ,

   I need to add some custom column in the POWL list and for that I already did the following steps.

I am getting error while try to call get actions method for calling the custom POWL application.

Steps -

1> Created custom structure and include  USMD_S_CREQUEST_POWL structure

2> Created custom TABLE TYPE and maintain custom structure as LINE TYPE

3> Copied  feeder Class CL_USMD_CREQUEST_POWL into custom feeder class.

4> Maintained custom application in transaction FPB_MAINTAIN_HIER

5> Created powl type in transaction POWL_TYPE with custom feeder class.

6> Created powl query in transaction POWL_QUERY with custom query id & powl id

7> Created custom COMPONENT CONFIGURATION from WD component IBO_WDC_INBOX

8> Created custom APPLICATION CONFIGURATION from WD component IBO_WDC_INBOX and assigned configuration.

9> Maintained application , role , powl type in transaction POWL_TYPER

10 > Maintained application , query in transaction POWL_QUERYR and activated.

11 > Maintained Application configuration in role .

12 > Added Custom coding in method GET_OBJECTS & GET_ACTIONS.

Got error  ' Object does not contain an interface '  in the follwoing method calling -

CALL METHOD super->if_powl_feeder~get_actions

EXPORTING

i_username = i_username

i_applid = lv_applid

i_type = lv_type

i_selcrit_para = i_selcrit_para

* i_langu = SY-LANGU

* IMPORTING

* e_actions_changed =

CHANGING

c_action_defs = c_action_defs

Please guide me to resolve the same or the way I can add the custom column in powl list.

Thanks in advance .

Don't copy class CL_USMD_CREQUEST_POWL. Instead, create a child class and redefine those methods you need to modify.

Dear Sanarat,

based on your error and  you have copied the class  CL_USMD_CREQUEST_POWL but you need to define the interface for this classe so that the standard proram need to understand how to access this class.

Please refer to the below link for further clarification.

Hi Shankar ,

   In the custom feeder class there is a interface IF_POWL_FEEDED and trying to accessing the method of that interface.

Could you clarify the in details that how can we resolve the interface issue?

Thanks in advance .
