i hope that u want 2 retrieve the fieldname of standard sap tables and not internal table

use this function module FMRE_GET_TABLEFIELDS_LONGNAMES

and pass the table name of which u want the fields and u will get the fieldnames

hi,

try in DD03L table

data itab type standard table of dd03l with header line.

select TABNAME

fieldname

into table itab

where tabname = 'VBAK'.

Hi,

you can use the fm CEV3_TABLE_READ to get all fields of a table.

To get all tables, read table DD02L.

How to declare the internal table to hold this fieldname.?

[Former Member]

Hi Gary,

Use the function module

DDIF_FIELDINFO_GET

To declare the the internal table with the desired fields.

let us suppose take table T549A. if you want all fields of that table.

declare it as shown below.

<b>Method1:</b>

DATA: Begin of itab occurs 0.

include structure T549A.

DATA: End of itab.

<b>Method2:</b>

data: itab like t549a occurs 0 with header line.

if you want only specific fields from that table

declare it as shown below.

DATA: Begin of itab occurs 0,

abkrs like t549a-abkrs,

permo like t549a-permo,

end of itab.

Hope you understand.
