Hi Venkat,

The better way is use

SY-DBCNT.        ------> DB operations, number of table lines processed

Hi,,,,,,

Your question is not clear, By other selection screen means Other Report selection screen, if this is the case then you can use "SUBMIT" statement. check the syntax with SAP Help.

My question is how to select data from table which is given as input in the selection screen

[Former Member]

copy the value of selection screen to some string variable say table_name

then write select query like

select * from (table_name) upto 100 rows.

you can also write like upto n row's

[Former Member]

Hi Venkat,

You have to use Field symbols in order to fetch the records at run time or dynamically.

Please, go through it.

Thanks santosh, but if i need to use where condition, how to compare the table fields which we do not know until runtime, can you please help in this case.

HI

Refer this code.

initialization.

**Selection screen for Input screen.

selection-screen begin of block b with frame title text-001.

select-options: s_werks for aufm-werks obligatory, "Plant

selection-screen end of block b.

if s_werks is not initial and s_budat is not initial.

Fetch the Order Number from table AUFNR.

select mblnr

mjahr

zeile

werks

aufnr

from aufm

into table it_aufm

where werks in s_werks

and budat in s_budat

and aufnr in s_aufnr.

if sy-subrc <> 0.

message 'Value is not avalibale as per you INPUT' type 'E'.

endif.

else.

message 'Plant and Posting date both are mandatory' type 'E'.

endif.

hI,

You can find the table fields in table DD03L.

Hello Venkat,

Do you think this is a logical requirement?

You can get the fieldnames of the table from DD03L, but you need to have values to use against these fields. How to you intend to do this @ runtime? (Santosh your comments on this issues)

Can you plz elaborate what's ur actual requirement is ?

BR,

Suhas

Hi Venkat,

You can give your conditions dynamically with dynamic table name as below,

TABLES: vbak.

DATA: t_vbak TYPE STANDARD TABLE OF vbak,
      wa_vbak LIKE LINE OF t_vbak.

TYPES: ty_field(50) TYPE c,
       ty_cond  TYPE TABLE OF ty_field.

DATA: t_cond TYPE ty_cond, "Internal table to store conditions
      wa_cond TYPE ty_field.

DATA: w_tab TYPE tabname VALUE 'VBAK'.

SELECT-OPTIONS: so_vbeln FOR vbak-vbeln. "Input selection screen

wa_cond = 'VBELN IN SO_VBELN '. "Giving the condition
APPEND wa_cond TO t_cond.

SELECT * FROM (w_tab)
  INTO TABLE t_vbak
  WHERE (t_cond). "<=This is same as  'WHERE VBELN IN SO_VBELN'

WRITE: / 'Number of records : ' , sy-dbcnt.
WRITE: / 'VBELN'.
LOOP AT t_vbak INTO wa_vbak.
  WRITE:  / wa_vbak-vbeln.
ENDLOOP.

Hi Venkat,

example for data selection based on the input field:

here Inpit value is Purchase requisition number(BANFN)

selection criteria

select * from EBAN in to table itab

where BANFN EQ P_BANFN.

p_banfn is input value.

or provide me your selection criteria.
