hi all,

when we click on text-001 we get symbols, selection texts and list headings. Can anyone explain what is the use of list headings with example. What is the text-001 called as.

what is the difference between the following:

1. data itab_wa type line of itab and type itab_wa like line of itab.

2. type v_matnr like mara-matnr and data v_matnr like mara-matnr

thanks

List heading is used to write column headings.

text-001 is called <b>Text Element.</b>

When we click on text-nnn, we get

1. Text symbols : here you can give the description of the number given.

2.Selection texts : here you give the description of selection screen fields.

<b>3.List headings : If you specify anything here, it will be displayed as report heading of the output.</b>

<b>Diff</b>

<b>so you are asking the difference between types and data</b>

like -> used for refering existing data elements in data dictionary or in sap

type -> used for refering existing data types in sap.

types: used for creating used defined structure of tables which has fields from more tahn one table.

diff b/w types and type in creation of internal tables is that when u create a table with types then u can use same for work area creation also.

ex:

TYPES : BEGIN OF t_vbap,

vbeln1 LIKE vbeln,

posnr LIKE posnr,

kwmeng LIKE kwmeng,

netpr LIKE netpr,

netwr LIKE netwr,

werks LIKE werks,

matnr LIKE matnr,

arktx LIKE arktx,

END OF t_vbap.

data: itab1 type t_vbap

wa_itab1 type t_vbap.

when type is used then u have to create a defintion of work area for another time when internal table doesnt have headr line as

ex:

DATA : BEGIN OF t_vbap OCCURS 0,

vbeln1 LIKE vbap-vbeln,

posnr LIKE vbap-posnr,

kwmeng LIKE vbap-kwmeng,

netpr LIKE vbap-netpr,

netwr LIKE vbap-netwr,

werks LIKE vbap-werks,

matnr LIKE vbap-matnr,

arktx LIKE vbap-arktx,

END OF t_vbap.

DATA : BEGIN OF wa_vbap,

vbeln1 LIKE vbap-vbeln,

posnr LIKE vbap-posnr,

kwmeng LIKE vbap-kwmeng,

netpr LIKE vbap-netpr,

netwr LIKE vbap-netwr,

werks LIKE vbap-werks,

matnr LIKE vbap-matnr,

arktx LIKE vbap-arktx,

END OF wa_vbap.

TYPES is used when you want to create a struture

DATA is used when you want to create an internal table or simple data types

TYPES : begin of ty_itab,

matnr like mara-matnr,

maktx like makt-maktx,

end of ty_itab.

data : itab type table of ty_itab.

Hi,

Regarding following questions -

what is the difference between the following:

1. data itab_wa type line of itab and type itab_wa like line of itab.

2. type v_matnr like mara-matnr and data v_matnr like mara-matnr

Here is the answer -

he syntax and meaning of the additions TYPE and LIKE are completely equal for both statements with the exception that TYPES creates an independent reference type, whereas DATA creates a bound reference type.

For further details and additions to this topic, see the keyword documentation.

hi Samir,

when you click on tex-001 u get screen .Under Text symbols you write in columns :

Symbol Text

001 Purchase order(this will become the heading on o/p screen).

In selection text

Name Text

(name will be Under this write the name for variable u r

filled automatically by variable using.

u r using).

Look at eg below -->

selection-screen Begin of block block1 with frame title text-111.

select-options : S_EBELN for EKPO-EBELN.

selection-screen end of block block1.

Under text symbol i wrote :

Symbol Text

001 Purchase order

Under selection scrreen i wrote :

Name Text

S_EBELN PURCHASE ORDER NO :

Coming to 2 nd question :

when u use data itab_wa type line of itab : here type makes itab_wa structure similar to that of itab.

when u use data itab_wa like line of itab. : here like makes itab_wa an internal table that stores temporary data in that program.

Thanks ...Plz reward if useful.
