How can I list all the column names of a table dynamically by programming?

[Former Member]

Hi,

Now I want to write an function using ABAP which has the following features:

Firstly, The function was given a parameter as table name.

Then, it will lists all the columns names of the table.

e.g

table: person

---firstName------lastName----+

Michale Jackson

.... ....

We can get the columns 'firstname' and 'lastName' by calling the function with table name 'person'.

And I also wonder that where I can get reference book or any other materials?

Thanks.

Hi

No need to write any Function..U can get same feature by using

RFC_READ_TABLE

Hi, You need not create an explicit function for field name descriptions. SAP internally has quite few FM's for the same. One FM is: C14Z_TABLE_INFO_GET Once executed you can find the descriptions in following fields of the internal table

DDTEXT
REPTEXT
SCRTEXT_S
SCRTEXT_M
SCRTEXT_L
