selection-screen event

[Former Member]

hello,

1. I an using a BAPI in the start-of-selection event .

2. For this BAPI we have a return parameter .

3. If i get a return parameter other than SUCCESS message type I have to display an error message on the selection-screen .

4. The requirement was I need to show this BAPI as an selection-screen event it seeems.

is it posible ?

[former_member186741]

it's possible. Just code it there. SHow the first entry of return as an error message.

But you'll have to be careful. You probably don't want to always run the bapi but control it by the pfkey used.

hello,

i have coded like this -->

**********************************************************

FORM get_price_details .

• Call bapi to get the price details

CALL FUNCTION '/BSHS/SOM_OPEC_SIMULATE_ORDER' DESTINATION p_rfcdes

EXPORTING

import_fixdata = i_fixdata "customer

import_header = i_header

import_man_adress = i_man_adress

IMPORTING

return = e_bapi_return

TABLES

import_items = x_import_items "material

export_atpquantities = x_export_atpquantities

export_pricecondit = x_export_pricecondit

import_atpplants = x_import_atpplants

import_partners = x_import_partners "customer type

export_partners = x_export_partners

import_pricecondit = x_import_pricecondit "price cond

export_items = x_export_items.

• To give a message to the user if the BAPI fails to

• fetch the data

IF e_bapi_return-type NE 'S' and

e_bapi_return-type eq space.

• MESSAGE e000(/bshm/ap_msg) DISPLAY LIKE 'S'

• WITH e_bapi_return-message.

MESSAGE e000(/bshm/ap_msg)

WITH e_bapi_return-message.

STOP.

ENDIF.

********************************************************

if i code like this it is displaying the message on the blank screen instead of the selection-screen

what would be the reason ?

Hi sandeep,

1. Yes, its possible.

2. We have to use just one statement extra.

LEAVE LIST-processing.

3. like this.

START-OF-SELECTION.

-

---

CALL BAPI

IF SY-SUBRC <> 0 "-----ERROR

MESSAGE.......

<b> LEAVE LIST-PROCESSING.</b>

ENDIF.

hello amit ,

the message was displaying in the status bar itself .

but on the blank-selection-screen instead of the selection-screen filled with selection-parameters.

i think leave list-processing is used to leave a list.

but here i don't have a list .

it is an ALV program

[Former Member]

Hi again,

1. Whether ALV list or normal list using write statement,

we have to use

LEAVE LIST-PROCESSING

(This statement cancels further processsing,

and returns back to selection screen).

2. To get a taste of it,

just copy paste in new program.

(on screen, enter 'X'

so that it goes further,

IF left blank,

it will give MESSAGE)

3.

report abc.

*----

---

parameters : a type c.

start-of-selection.

if A <> 'X'.

message 'wrong entry' type 'I'.

leave list-processing.

endif.

write : 'successs'.

FORM get_price_details .

• Call bapi to get the price details

CALL FUNCTION '/BSHS/SOM_OPEC_SIMULATE_ORDER' DESTINATION p_rfcdes

EXPORTING

import_fixdata = i_fixdata "customer

import_partners = x_import_partners "customer type

export_partners = x_export_partners

import_pricecondit = x_import_pricecondit "price cond

export_items = x_export_items.

• To give a message to the user if the BAPI fails to fetch the data

IF e_bapi_return-type NE 'S' and

e_bapi_return-type eq space.

• MESSAGE e000(/bshm/ap_msg) DISPLAY LIKE 'S'

MESSAGE e000(/bshm/ap_msg)

STOP.

leave list-processing.

ENDIF.

*******************************************************

but still the problem persists ./..

what to do ?

[Former Member]

Hi again,

1. Just make this small changes,

indicated in bold.

(the message type should be S , I ,W

But NEVER 'E' )

(Remove STOP )

2.

<b>MESSAGE I000(/bshm/ap_msg)</b> "--- Note I (not E)

WITH e_bapi_return-message.

<b>* STOP. "-----Comment this line</b>

leave list-processing.

Hi Sandeep,

Use something like this to display the error message.

• Read the return table for the error type 'E'.

if sy-subrc eq 0.

MESSAGE ID 'Message_Class'

TYPE 'S'

NUMBER '021'

DISPLAY LIKE 'E'.

EXIT.

ENDIF.

This will solve your problem.

Hi Sandeep,

I'm a bit confused by what you say

"the message was displaying in the status bar itself .

but on the blank-selection-screen instead of the selection-screen filled with selection-parameters."

I think you mean that NO selection screen is shown. But a blank sap screen with the message on the bottom status line. This is standard behaviour for an E message issued from the start-of-selection event.

1. Change your message to an 'S' (this will make it appear on the next screen shown).

2. Instead of the STOP, do this.

data w_seltab type table of rsparams.

• get the selection-screen values as entered by the user

CALL FUNCTION 'RS_REFRESH_FROM_SELECTOPTIONS'

EXPORTING

curr_report = sy-repid

• IMPORTING

• SP =

tables

selection_table = w_seltab

EXCEPTIONS

NOT_FOUND = 1

NO_REPORT = 2

OTHERS = 3

.

• this submits the current abap, shows the sel screen

• with the values entered by the user

submit (sy-repid) via selection-screen

WITH SELECTION-TABLE w_seltab .

the message type which you are using is e, try using i.
