MODIFIYNIG DYNAMIC INTERNAL TABLE

Former Member — Mon, 24 Sep 2007 07:00:55 GMT

I have created a dynamic internla table and was able to puplulate data init but could not do it in a way i wanted ...

Please have a look at the code and read the rest of the doubt

REPORT yms_dynamicalv.

TABLES : mara .

TYPE-POOLS: slis.

FIELD-SYMBOLS: <dyn_table> TYPE STANDARD TABLE,

<dyn_wa>.

FIELD-SYMBOLS: <dyn_table2> TYPE STANDARD TABLE,

DATA : BEGIN OF itab OCCURS 0 , "Based on the values in this tabel dynamic

mtart LIKE mara-mtart , "table coulmns will be generated

END OF itab .

DATA : BEGIN OF itab2 OCCURS 0 , "This is a normal internal table from which

hai(5) TYPE c, " i have to populate data into the dynamic

field2(5) TYPE c, "internal table

mtart LIKE mara-mtart ,

matnr LIKE mara-matnr ,

END OF itab2 .

DATA: alv_fldcat TYPE slis_t_fieldcat_alv,

it_fldcat TYPE lvc_t_fcat,

lin TYPE i .

new_line TYPE REF TO data,

START-OF-SELECTION.

SELECT

mtart

FROM mara INTO CORRESPONDING FIELDS OF

TABLE itab

WHERE mtart IN s_mtart .

DELETE ADJACENT DUPLICATES FROM itab.

*This select enables dynamic values in itab but commented for simplicity in fixing

*the problem instead appended 6 rows of data

SELECT
matnr
mtart
FROM mara INTO CORRESPONDING FIELDS OF
TABLE itab2
WHERE mtart IN s_mtart .

itab2-hai = 'FIRST'.

itab2-field2 = 'A'.

itab2-mtart = 'FERT'.

The above code populates data as follows

HAI | field2 | FERT | FGTR | HALB | HAI2 | HAI3

______________________________________________________________

FIRST FIRST FF000001

FIRST FIRST FH000001 FH000001 FH000001

SEC SEC SF000002

SEC SEC SH000002 SH000002 SH000002

THIR THIR TH000003 TH000003 TH000003

THIR THIR TFG000003

But the Out put required should be as follows

HAI | field2 | FERT | FGTR | HALB | HAI2 | HAI3

____________________________________________________________________

FIRST | FIRST |FF000001 | |FH000001

SEC |SEC |SF000002 | |SH000002

THIR |THIR | |TFG000003 |H000003

The layout may be bit confusing to put simply ..FF00001--means First Field's FERT material no similarly SH00002 means second fields HALB material number the materila numbers should come under their sorresponding material type .

Hope my question is clear .....

For the sake of simplicity i have inserted 6 record into the internal table from which iam passing into a DYNAMIC INTERNAL TABLE ..

This code has no dependencies hence try it in ABAP editor if necessary and pelase give me solution ..

Thanking you inadvance .

hi Suriya,

I am not sure if anyone will do your job (i. e. debugging your own program), but few things are definetly wrong:

wa_it_fldcat-tabname = itab.

Here you assign the whole table (with values) instead of the name of the table. On the other hand, you have to assign a tablename from the Data Dictionary, you cannot do with internal table name.

wa_it_fldcat-fieldname = itab-mtart.

Again, you assign a value (like 'FERT'), instead of assigning the name of the field (which you cannot do this way).

wa_it_fldcat-datatype = itab2-matnr.

Again...

Pls. correct these first and come back if you have more questions.
