Re: What do 'GetEntitySet (Query)' & 'GetEntity (Read)' do.

Thanks a lot Ekansh.

I have now almost implemented both getEntitySet() & also getEntity() methods.

getEntitySet() is working fine when I use below URL.

http://<Netweaver Gateway domain>:8000/sap/opu/odata/sap/ZUI5_SAMPLEUSERINFO_SRV/UserInfoSampleSet

I have also implemented getEntity() method to read a particular record. Below is the code which I have written inside getEntity() method.

******************

method USERINFOSAMPLESE_GET_ENTITY.

data : ls_key_tab   TYPE /iwbep/s_mgw_name_value_pair,

        lc_userInfo_struct type ZUSERINFO_STRUCT,

        lc_userId type zuser_info-zuserid,

        lc_addr type zuser_info-zaddr,

        lc_userinfo_it TYPE  zuser_info.

READ TABLE it_key_tab WITH KEY name = 'USERID' INTO ls_key_tab.

lc_userId = ls_key_tab-value.

select single * from zuser_info into lc_userinfo_it where zuserid = lc_userId.

IF sy-subrc = 0.

   er_entity-zuserid = lc_userinfo_it-zuserid.

   er_entity-zaddr = lc_userinfo_it-zaddr.

   er_entity-zcountry = lc_userinfo_it-zcountry.

ENDIF.

   endmethod.

But now when I try below URL to get particular record, I am getting below error.

http://<Netweaver Gateway domain>:8000/sap/opu/odata/sap/ZUI5_SAMPLEUSERINFO_SRV/UserInfoSampleSet('123098')
