RFC Function Module

Former Member — Wed, 25 Mar 2009 15:25:03 GMT

Hello,

I am trying to get the records using RFC FM in IT_DATA[] using the following. But I am not getting any records in it. it_data is declared as (DATA: it_data TYPE tab512 OCCURS 0 WITH HEADER LINE.)

LOOP AT it_rseg_data.

it_options-text = 'BELNR = '.

CONCATENATE ' '' ' it_rseg_data-belnr ''' AND ' INTO objid.

CONDENSE objid NO-GAPS.

CONCATENATE it_options-text objid INTO it_options-text

SEPARATED BY space.

APPEND it_options.

ENDLOOP.

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

IT_OPTIONS gets built with different values of BELNR from it_rseg_data table.

For Ex. BELNR = 1234

BELNR = 5678

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

PERFORM read_rbkp_belnr_details USING p_logsys bldat bldat_to.

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

FORM read_rbkp_belnr_details USING p_logsys LIKE rfcdes-rfcdest bldat bldat_to.

DATA: l_errflg TYPE char1. CLEAR: it_data. REFRESH: it_data.

CHECK NOT vt_fields[] IS INITIAL.

read data from backend

PERFORM read_table_rbkp_for_belnr USING 'RBKP'

p_logsys bldat bldat_to

CHANGING l_errflg.

ENDFORM.

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

FORM read_table_rbkp_for_belnr USING pi_tabname LIKE dd02l-tabname

pi_logsys bldat bldat_to

CHANGING pc_errflg.

REFRESH it_data. CLEAR it_data.

CALL FUNCTION 'RFC_READ_TABLE'

DESTINATION PI_LOGSYS

EXPORTING

query_table = 'RBKP'

TABLES

OPTIONS = it_options

fields = vt_fields

data = it_data

EXCEPTIONS

table_not_available = 1

table_without_data = 2

option_not_valid = 3

field_not_valid = 4

not_authorized = 5

data_buffer_exceeded = 6

OTHERS = 7.

it_rbkp_data [] = it_data [].

Shall appreciate if anyone can tell me where I am doing wrong and how do I correct it.

Thks,

Hemal

I think problem is while creating the options internal table


LOOP AT it_rseg_data.
it_options-text = 'BELNR = '.
CONCATENATE ' '' ' it_rseg_data-belnr ''' AND ' INTO objid.
CONDENSE objid NO-GAPS.
CONCATENATE it_options-text objid INTO it_options-text
SEPARATED BY space.
APPEND it_options.
ENDLOOP.

Say for example if you are inserting for BELNR 1000 then after your loop

it looks like


BELNR = '1000' AND.

I think you need to remove the AND from the last record

Also makesure rfc destination 'pi_logsys' is case sensitive.

Try to run your RFC FM, in standalone mode through SE37 and check why the data is not getting populated.

Thanks for the response. Even though I remove AND, it does not fill it_data. Is there any other thing I can do so that the RFC FM sends it to the backend table (RBKP.)

Rgds,

Try it thru SE37 with same values u are passing thru program and check

This FM looks like taking one value at a time. Is there any other FM that would take multiple different entries and retrieve the respective records ?
