[ECC6] Inserting data from internal table (deep structure) into db table

[Former Member]

Hi experts,

I have a problem when inserting data from IT using deep structure into a database table. Please help:

I have one database table with 2 columns ZTest (col1, col2). Col1 is key.

In my program I have a deep structure t_screen using table type lvc_t_scol:

In 4.6c systems, the INSERT statement works well but it does not work in ECC6 systems.

DATA: BEGIN OF t_screen OCCURS 0,
        rec_count(3) TYPE n,
        col1 LIKE ZTest-col1,
        col2 LIKE ZTest-col2.
DATA: ct TYPE lvc_t_scol.
DATA: END   OF t_screen.
 
t_screen-col1 = 'test1'.
t_screen-col2 = 'test1'.
APPEND t_screen.
 
t_screen-col1 = 'test2'.
t_screen-col2 = 'test2'.
APPEND t_screen.
 
INSERT ZTest FROM TABLE t_screen ACCEPTING DUPLICATE KEYS.

Currently I have an idea using a temporary internal table with the same structure as ZTest. Use MOVE-CORRESPONDING statement to move data from t_screen table to temporary table before inserting --> It worked. But do you have any ideas without using temporary table?

HI,

Check the below code...

DATA: BEGIN OF t_screen OCCURS 0,
        rec_count(3) TYPE n,
        col1 LIKE ZTest-col1,
        col2 LIKE ZTest-col2.
DATA: ct TYPE lvc_t_scol.
DATA: END   OF t_screen.
 
DATA  it_ct TYPE lvc_t_scol,
           ct_line LIKE LINE OF it_ct.

ct_line-FNAME = 'FNAME1'.
ct_line-color  = 'COLOR1'.
APPEND CT_linE to IT_CT.

ct_line-FNAME = 'FNAME2'.
ct_line-color  = 'COLOR2'.
APPEND CT_linE to IT_CT.

t_screen-col1 = 'test1'.
t_screen-col2 = 'test1'.
t_screen-ct[] = IT_CT[].
APPEND t_screen.

REFRESH IT_CT.

ct_line-FNAME = 'FNAME3'.
ct_line-color  = 'COLOR3'.
APPEND CT_linE to IT_CT.

ct_line-FNAME = 'FNAME4'.
ct_line-color  = 'COLOR4'.
APPEND CT_linE to IT_CT.
 
t_screen-col1 = 'test2'.
t_screen-col2 = 'test2'.
t_screen-ct[] = IT_CT[].
APPEND t_screen.
 
INSERT ZTest FROM TABLE t_screen ACCEPTING DUPLICATE KEYS.

Hi Kodarapu,

Thanks for your reply.

The problem is not because of lacking sample data.

The problem is syntax error when I compile the following code in ECC6 system.

INSERT ZTest FROM TABLE t_screen ACCEPTING DUPLICATE KEYS.

Message as follow:

The work area (or internal table) "T_SCREEN" is not flat, or contains reference or internal tables as components. components. components. components. components.

Sorry for my unclear description.

Hi

There are a large number of stataments couldn't be supported in unicode system and so it doesn't allow to do it in ECC 6.

U need to delete the deep structure from your defination:

DATA: BEGIN OF t_screen OCCURS 0,
        rec_count(3) TYPE n,
        col1 LIKE ZTest-col1,
        col2 LIKE ZTest-col2.
DATA: ct TYPE lvc_t_scol. "<-------- Error is here
DATA: END   OF t_screen.

So u need to use a structure like this to update your table:

DATA: BEGIN OF T_ZTEST OCCURS 0,
        rec_count(3) TYPE n,
        col1 LIKE ZTest-col1,
        col2 LIKE ZTest-col2.
DATA: END   OFT_ZTEST.
