Create Data, UPdate statement problems in 4.6

[Former Member]

Hello Friends,

I was having with the create data statement to create an internal table. However as suggested by many here I hav used methods and FM to do the same and my internal table is creted.

However the problem is the Internal table created does not have the same

the table <f_table_update> has been created with 804 bytes memory. However MARA has 806 bytes of memory.

hence a short Dump is observed.

Shore Dump message

In this particular case, the database table is 806 bytes wide,

but the internal table is only 804 bytes wide.

data :       i_fcat         TYPE STANDARD TABLE OF lvc_s_fcat.
DATA: i_table_data1  TYPE REF TO data.
FIELD-SYMBOLS: <f_table_update>     TYPE STANDARD TABLE.

PARAMETERS: p_table TYPE tabname OBLIGATORY.

  CLEAR   i_fcat.
  REFRESH i_fcat.

Hi,

In debug, check the i_fcat returned by 'LVC_FIELDCATALOG_MERGE'.

Compare the structure it has returned with the MARA structure.

Hi,

After getting the field catalog from FM LVC_FIELDCATALOG_MERGE

try to increase the length (internal length and output length) of the last field in it by 2 character (in 4.6 c 1 char = 1 byte). Then try to update the table and check the result.

Regards,

Joy.

Any more suggestions.

I beleive it is the .INCLUDE s and APPEND s which create the issue.

made these changes..and is working..

data : t_dd03l like dd03l occurs 0 with header line.
data : GT_FIELDCAT type lvc_s_fcat.

select * from dd03l into corresponding fields of table t_dd03l
where tabname = p_table.
sort t_dd03l by position.
loop at t_dd03l where rollname ne space.
GT_FIELDCAT-FIELDNAME = t_dd03l-FIELDNAME.
GT_FIELDCAT-TABNAME   = p_table.
 APPEND GT_FIELDCAT to i_fcat.
endloop.

*  CALL FUNCTION 'LVC_FIELDCATALOG_MERGE'
*       EXPORTING
*            i_structure_name = p_table  " Table Name
*       CHANGING
*            ct_fieldcat      = i_fcat
*       EXCEPTIONS
*            OTHERS           = 1.
