Calling Parallel Processing From an RFC

[Former Member]

Hello,

We have a requirement where we need to perform parallel processing with in an RFC function(JAVA). However, on executing parallel processing inside an RFC we are getting an error that "Resource Failure".

Kindly guide, if it is possible to perform parallel processing within RFC function( called from JAVA)?

Hy Anurag,

Can you please post the code you using to perform you parallel processing call?

Which destination group are you using? Are you using the "parallel_generators"?

Did you check how many dialogue processes are available? (function modules : SPBT_INITIALIZE or SPBT_GET_CURR_RESOURCE_INFO )

Either way, here follows an example on parallel processing that I found on web some time ago. Note that this implementation might be unsafe, this code is not regarding the available resources:

*________________________________________________________

TABLES : MARA.

DATA : BAPIMATDOA TYPE BAPIMATDOA,

BAPIRETURN TYPE BAPIRETURN.

DATA : SYSTEM TYPE RZLLI_APCL,

taskname(8) type c,

index(3) type c,

snd_jobs TYPE i,

rcv_jobs TYPE i,

exc_flag TYPE i,

mess TYPE c LENGTH 80.

TYPES : BEGIN OF type_material,

desc TYPE maktx,

END OF type_material.

DATA : Material type table of type_material with header line.

SELECT-OPTIONS S_MATNR FOR MARA-MATNR.

CONCATENATE ‘Task’ index into taskname. ” Generate Unique Task Name

CALL FUNCTION ‘BAPI_MATERIAL_GET_DETAIL’ STARTING NEW TASK taskname

EXPORTING

resource_failure = 3.

CASE sy-subrc.

WHEN 0.

snd_jobs = snd_jobs + 1.

WHEN 1 OR 2.

MESSAGE mess TYPE ‘I’.

WHEN 3.

IF snd_jobs >= 1 AND

exc_flag = 0.

exc_flag = 1.

WAIT UNTIL rcv_jobs >= snd_jobs

UP TO 5 SECONDS.

ENDIF.

IF sy-subrc = 0.

exc_flag = 0.

ELSE.

MESSAGE ‘Resource failure’ TYPE ‘I’.

ENDIF.

WHEN OTHERS.

MESSAGE ‘Other error’ TYPE ‘I’.

ENDCASE.

ENDLOOP.

WAIT UNTIL rcv_jobs >= snd_jobs.

loop at material.

write : material-desc.

endloop.

form set_function1_done using taskname.

rcv_jobs = rcv_jobs + 1.

receive results from function ‘BAPI_MATERIAL_GET_DETAIL’

IMPORTING

MATERIAL_GENERAL_DATA = BAPIMATDOA.

BAPIRETURN = BAPIRETURN.

functioncall1 = done.

APPEND bapimatdoa-matl_desc TO material.

ENDFORM.

Hello José,

Pasting Source Code below, I used in my code:

CALL FUNCTION 'ZSQP_GET_CONFIG_PRICE'

     STARTING NEW TASK 'SANITY_CHECK'

     DESTINATION IN GROUP DEFAULT

     PERFORMING get_result ON END OF TASK

     EXPORTING

       iv_customer           = piv_customer

       iv_package_type       = piv_package_type

       iv_body_size          = piv_body_size

       iv_layer              = piv_layer

       iv_wire_mat_cost      = piv_wire_mat_cost

       iv_substrate_cost     = piv_substrate_cost

       iv_leadframe_cost     = piv_leadframe_cost

     EXCEPTIONS

       communication_failure = 1

       system_failure        = 2.

FORM get_result USING taskname.

   DATA : lt_return  TYPE bapiret2_t.

   RECEIVE RESULTS FROM FUNCTION 'ZSQP_GET_CONFIG_PRICE'

     IMPORTING

       et_ref_price = gt_price

       et_return    = lt_return

     EXCEPTIONS

       communication_failure = 1

       system_failure = 2.

   CLEAR gv_return.

ENDFORM.                    "get_result

"Get Reference Price

WAIT UNTIL gv_return IS INITIAL.

et_ref_price[] = gt_price[].

Hello Anurag,

Try to change the:

DESTINATION IN GROUP DEFAULT

to

DESTINATION IN GROUP system

note: System has to be declared and filled:

DATA : SYSTEM TYPE RZLLI_APCL.

system = ‘parallel_generators’.

Check in t-code RZ10 if you have set the group server parallel_generators. If it's not set, use one destination set there.
