Hi,

it is easy,

you can assign your data ( type ref to data ) to hashed table,

and then pass your hased table to method with parameter hashed table

try this code to understand, hopfully will help you.

REPORT ztest200.

DATA: lr_data TYPE REF TO data,
lt_tab TYPE HASHED TABLE OF mara
WITH UNIQUE KEY matnr.

FIELD-SYMBOLS <lt_data> TYPE HASHED TABLE.

START-OF-SELECTION.

ASSIGN lt_tab TO <lt_data>.

CREATE DATA lr_data LIKE <lt_data>.
ASSIGN lr_data->* TO <lt_data>.

SELECT * FROM mara INTO TABLE <lt_data> UP TO 10 ROWS.

zibo_cl_test=>pass_hash_table( it_data = <lt_data> ).

BREAK-POINT.

If you want to pass the LR_DATA ( type ref to data) to hash table, I don't think that you can, because they have difference data type , so you have to pass the ref to dynamic table

assign ref to <lt_data>.. as I have written in Code

look to this syntax error while i was trying to pass ref_data to hash table through method.

Hi,

Thanks for ur detail reply.

why do you declare lt_tab with hashed table of mara with unique key matnr.

because hashed table in my method parameter it's generic. means it's like below.

it_data type hashed table

Hi,

it just an example to fill the ITAB, so if you need it as generic

you can use this

FIELD-SYMBOLS <lt_data> TYPE HASHED TABLE.

in method also I have defined as generic.

see the method,

I have only passed the data to the method ( hashed table generic)

Hi,

my code is as below.

Data: lt_data type ref to data.

field-symbols: <it_hash_data> type hashed table.

after calling some standard method i will get data into lt_data. (i don't know unique in this)

then this data lt_data i have to pass to method parameter (let say it_hash_data which is of type hashed table).

step1:

step2: create data lt_data like <it_hash_data>.

step3 : assign lt_data->* to <it_hash_data>.

step1 is not clear for me. can you please guide. thanks.

Venkat

Hi,

yes are right, you dont know about which unique key,

so you have to the following steps,

1. Data: lt_data type ref to data.

field-symbols: <it_hash_data> type hashed table.

so. hier you call standard method and you will get lt_data (ref to data ) goooood.

now lt_data ( has entries and you want to pass to method type hashed table)

ASSIGN lt_data->* TO <it_hash_data>.

call you method

pass_hash_table( it_data = <it_hash_data> ).

and it works ,

I have tried it out, and if you need the code I can send you.
