The tables are...

<b>DD02L - SAP tables

DD02T - R/3 DD: SAP table texts

DD03L - Table Fields

DD03T - DD: Texts for fields (language dependent)

DD04L - Data elements

DD04T - R/3 DD: Data element texts

DD01L - Domains

DD01T - R/3 DD: domain texts

DD07L - R/3 DD: values for the domains

DD07T - DD: Texts for Domain Fixed Values (Language-Dependent)

Transparent tables can be identified using DD02L-TABCLASS = 'TRANSP'.</b>

hope that gives you some starting point. Joining the tables together is some thing you will have to do looking at the contents of the table and taking a sample table intoaccount.

Hi,

Here is the code sample to see the table and its field.If you double click the table name,then you can go to SE11 and see the field descriptions from the program itself.Kindly reward points if it is useful.

TABLES: DD02L,

DD02T,

DD03L,

DD04T.

DATA: BEGIN OF ITAB_TABLES OCCURS 0,

TABNAME LIKE DD02L-TABNAME,

END OF ITAB_TABLES.

DATA: FILEOPENCANCELLED.

SELECTION-SCREEN: COMMENT 1(80) TEXT-001, SKIP 1,

COMMENT 1(80) TEXT-002, SKIP 1.

PARAMETER: TBLNAME LIKE DD02L-TABNAME.

IF TBLNAME IS INITIAL.

CALL FUNCTION 'UPLOAD'

EXPORTING

FILENAME = 'tablenames.txt'

IMPORTING

CANCEL = FILEOPENCANCELLED

TABLES

DATA_TAB = ITAB_TABLES.

IF NOT FILEOPENCANCELLED IS INITIAL.

EXIT.

ENDIF.

ELSE.

CLEAR ITAB_TABLES. REFRESH ITAB_TABLES.

ITAB_TABLES-TABNAME = TBLNAME.

APPEND ITAB_TABLES.

ENDIF.

SORT ITAB_TABLES.

DELETE ADJACENT DUPLICATES FROM ITAB_TABLES.

TRANSLATE ITAB_TABLES-TABNAME TO UPPER CASE.

SELECT TABNAME DDTEXT FROM DD02T

INTO CORRESPONDING FIELDS OF DD02T

FOR ALL ENTRIES IN ITAB_TABLES

WHERE TABNAME = ITAB_TABLES-TABNAME AND

DDLANGUAGE = 'E'.

FORMAT COLOR COL_KEY.

WRITE: / 'N ' AS SYMBOL,

DD02T-TABNAME RIGHT-JUSTIFIED, '-', DD02T-DDTEXT,

'? ' AS SYMBOL.

HIDE DD02T-TABNAME.

FORMAT COLOR OFF.

SELECT FIELDNAME ROLLNAME DATATYPE LENG DOMNAME FROM DD03L

INTO CORRESPONDING FIELDS OF DD03L

WHERE TABNAME = DD02T-TABNAME.

SELECT DDTEXT FROM DD04T

INTO CORRESPONDING FIELDS OF DD04T

WHERE ROLLNAME = DD03L-ROLLNAME AND

DDLANGUAGE = 'E'.

WRITE: /

DD03L-FIELDNAME, DD03L-ROLLNAME,

DD03L-DATATYPE, DD03L-LENG NO-ZERO,

DD03L-DOMNAME, (35) DD04T-DDTEXT.

ENDSELECT.

ENDSELECT.

ULINE.

ENDSELECT.

CLEAR DD02T-TABNAME.

AT LINE-SELECTION.

IF NOT DD02T-TABNAME IS INITIAL.

call function 'RS_DD_DEF_SHOW'

EXPORTING

OBJNAME = DD02T-TABNAME.

ENDIF.

CLEAR DD02T-TABNAME.

Hi.

If you use the table names from DD02L, you can then get the structure etc. using the Run Time Type System (RTTS):

DATA: l_tablename   TYPE        DD02L-TABNAME,
      l_structdescr TYPE REF TO CL_ABAP_STRUCTDESCR,
      l_comp_tab    TYPE CL_ABAP_STRUCTDESCR=>COMPONENT_TABLE.

l_structdescr ?= CL_ABAP_TABLEDESCR=>DESCRIBE_BY_NANE( l_tablename ).
l_comp_tab     = l_structdescr->get_components( ).
