select-option

[Former Member]

Hi,

Program to enable user to enter data and display data.

Define the following Parameters and Select-options:

Field Type Length Default Value Assign Value

P_PARAM1 I ‘959’

P_PARAM2 C 30

S_MATNR MARA-MATNR

P_DATE D SY-DATUM

select option for s_matnr

LOOP AT S_MATNR.

WRITE:/ S_MATNR-LOW.

ENDLOOP.

After writing the program it is showing the error that:

"Structures with components that are not character type can not be displayed on the selection screen".

Thanks

Try like this,

tables: mara.

parameters: P_PARAM1 type I default 959,

P_PARAM2(30) type C .

select-options S_MATNR for MARA-MATNR .

parameter: P_DATE like SY-DATUM .

LOOP AT S_MATNR.

WRITE:/ S_MATNR-LOW.

ENDLOOP.

Two questions arises in my mind:

1) why we need to write MARA-MATNR? what is meaning of that?

2) even without LOOP....END LOOP I can execute the program, so what is the requirement for this?

Thanks

Hi,

The reason why you require MARA-MATNR, is to inform which characteristics of data element of which table should the variable acquire.

For this you have to declare that table name in the TABLES declaration part. [ This is nothing but the work area for that table ].

Select-options are in the form of an internal table which has a structure of fields:

sign,

option,

low,

and high.

So all the values you enter in the select-options are stored in the form of an internal table. To read this internal table, you should use loop..endloop.

Hi,

tables: mara.

parameters: p_param type I default 959,

p_param2(30).

select-options : s_matnr for mara-matnr .

parameter: p_date like sy-datum .

loop at s_matnr.

write : / s_matnr-low.

endloop.

1. In Mara table matnr field is of type char whose length is 18

<b>select-options : s_matnr for mara-matnr</b>

here u r taking range of values of a variable of type char whose length is 18

if u r using select-options u have to mention table statement

tables : mara.

2. when ever u r entering values in s_matnr ( say 10 35 )

10 will be stored in s_matnr-low

35 will be stored in s_matnr-high

if u want to print s_matnr-low value u dont need loop and endloop.

directly u can write the statement

<b>write : / s_matnr-low.</b>

tables: mara.

parameters: p_param type I default 959,

p_param2(30).

select-options : s_matnr for mara-matnr .

parameter: p_date like sy-datum .

write : / s_matnr-low.

sorry i can not understand your actual requirement but if you want to display in outputn list then please use event start-of-selection and then use writhe command.

i think you are using some at selection-screen event.

start-of-selection.

LOOP AT S_MATNR.

WRITE:/ S_MATNR-LOW.

ENDLOOP.

try like this

tables : mara.

data : P_PARAM1 type I value 959,

P_PARAM2(30) type C,

P_DATE type SY-DATUM.

LOOP AT S_MATNR.

WRITE:/ S_MATNR-LOW.

ENDLOOP.
