REPLACE '&1' WITH wa_messtab-msgv1 INTO l_mstring.

REPLACE '&2' WITH wa_messtab-msgv2 INTO l_mstring.

REPLACE '&' WITH wa_messtab-msgv1 INTO l_mstring.

REPLACE '&' WITH wa_messtab-msgv2 INTO l_mstring.

REPLACE '&' WITH wa_messtab-msgv3 INTO l_mstring.

The meaning of the code is

t100 is a message table.

getting a message text from the message table.

if the message text contains '&1'

then replace &1 with msgv1

.....................................&2................................msgv2

so on.

if it does not contain &1 &2 buit contains only & then

replcace & with msgv1 and msgv2 so on according to the position of the &.

in general

If there is only one & it is replaced with msgv1.

2nd position with msgv2 , 3rd & with msgv3 4th with msgv4.

observe t1000 table and also go to se91 transaction and obseve.

&1...&4 will be replaced with sy-msgv1...sy-msgv2.

in ur report u can fill the fn module like below

the function module is

CALL FUNCTION 'MESSAGE_TEXT_BUILD'

EXPORTING

msgid = < enter the message class>

msgnr = < enter the message number

MSGV1 = wa_messtab-msgv1

MSGV2 = wa_messtab-msgv2

MSGV3 = wa_messtab-msgv3

MSGV4 = wa_messtab-msgv4

IMPORTING

MESSAGE_TEXT_OUTPUT = l_mstring.

Hi saurabh,

SAP loves ikt to make simple tasks complicated and time-consuming.

why not simplify:


data:
  lv_msg type string.
message ID    wa_messtab-msgid
              TYPE wa_messtab-msgty
              NUMBER wa_messtab-msgno
              WITH
              wa_messtab-msgv1 
              wa_messtab-msgv2
              wa_messtab-msgv3 
              wa_messtab-msgv4
              INTO lv_msg.

I don't know what your task is. T100 is useful to search with SE16 if you want to find a message. You never need it in a program.

If you want a message text (in logon language) just used MESSAGE ... INTO.
