CMOD-Datasource Enhancement

Question

Dear Experts,
i am doing the enhancement for the master data datasource 0CUSTOMER_ATTR.
i am using For All Entries when i am selecting the required data from the application table KNA1 and here the key field was KUNNR.
in the where condition which table we need to provide for " For All Entries" first i used the table I_T_DATA generally this will give us the data from the datasource.
i declared one internal table with type extract structure of datasource 0CUSTOMER_ATTR and used the same in For All Entries.
i am looping the table I_T_DATA  and getting the required data from internal table which i fetch from KNA1.
I am getting data for enhanced field when i checked teh same from RSA3,but when i debugged the code i am getting all the entries from KNA1 because the internal table whcih i used in For All Entries is blank.Since i am reading the Internal table from KNA1 only for each entry in I_T_DATA ,i am getting data only for selected records.
Please correct me if i am wrong and which table needs to be provided exactly in the where condition and the reason iam using the "For All Entries" to restrict the database for each record in I_T_DATA.

Hi Neeraj,
Please find the code.
TABLES : marc, mvke, knb1,kna1.
types : begin of ty_kna1,
            KUNNR                           type KUNNR,
           ZPASD_CRMACCOUNT  type ZPASD_CRMACC,
           end of ty_kna1.
data : ih_kna1 type  hashed table of ty_kna1 with unique key kunnr,
          wa_crmaccnt type ty_kna1,
select    KUNNR
              ZPASD_CRMACCOUNT
              from kna1
              into table ih_kna1
              for all entries in i_t_data
              where kunnr = i_t_data-kunnr.
the error is pointing to the select statement with error "The specified type has no structure and therefore no component called "KUNNR".i am using the Hashed table here.
