Select data from a structure

Former Member — Tue, 02 Oct 2007 21:57:52 GMT

Dear experts,

i am new to ABAP programming. I tried to create a function module and I would like to get some data from a structure but not from a table. Is it possible for me to do that using SQL statements in the 'source code'?

Thanks in advance

Hi,

The structure will not have any data..It is a just a template..You need to select the data from the database table

Thanks

Structure doesnt hold any data. It just has the fields in it.

You have to find the corresponding Table to find the data.

The structure will only have data if it has been loaded elsewhere, such as if the structure was populated by a function call or BAPI.

If not, you will have to load data into the structure using SQL Select or by calling the approriate function call/method/BAPI etc.

If the structure already has data, you access that data by referencing the structure name and the component

e.g.

w_field = struct-field1.

This will load the value of the component field "field1" in structure "struct" into a separate work field "w_field".

This is how you refer to components of a structure.

structure_name-component_name

Consequently, you should not use a dash "-" in the name of a field or structure. If you need to separate words in the name use an underscore "_".

If you do attempt to use the dash "-" in the name of a field or structure in a Unicode program, you will get a warning message.

Good luck
