problem populating an internal table

[Former Member]

Hello,

I am having a problem with filling an internal table. I cannot seem to grasp this and I struggle with this in every program. I am attaching pieces of my program so that maybe someone can help me. I have a selection screen that I populate with dates. if the dates are populated, I want to use these dates for the selection. If the dates are initial, I want to read an entry from the TVARV table and populate the dates that will used in the selection. I tried various code statements and I cannot get it to work. i get messages like "is a table without a header line and therefore has no component "LOW" or other messages similar to this. I would like that if the s_udate is populated, I could fill the tvarv table and not have to call the form.

also if anyone has some documentation on working with internal tables without header lines (I think I read in here that internal tables without header lines is the way to go ), could you please include that as well so that I could try to understand how this suppose to work

thanks in advance for the help

See the code below. I think you can do the reverse with s_update.

Darshil,

thanks for the reply.

I want to learn how to use use tables without header lines.

[Former Member]

In tables with header line, you need not define an explicit work area.

System will create a so-called work area, which is called header line.

This header line is like any other work area. the difference is that it can be accessed using internal table name. A record will be by default read into header line in a READ statement.

For ex,

READ TABLE p1_tvarv_date INTO wa_tvarv_date INDEX 1.

Here you used to read the 1st record into wa_tvarv_date.

But after making it table with header line you can use

READ TABLE p1_tvarv_date INDEX 1.

This will move the data to header line and it can be accessed by name p1_tvarv_date.

See the code below.

TYPES: BEGIN OF ty_tvarv_date,

low TYPE tvarv_val, "start date

high TYPE tvarv_val, "end date

END OF ty_tvarv_date.

TYPES: ty_t_tvarv_date TYPE STANDARD TABLE OF ty_tvarv_date INITIAL SIZE 0,
