Unable to create a subtask within a task for cProjects

Question

Hi All,
I am unable to create a subtask within a task using BAPI_BUS2175_CREATE. When I pass the GUID of the project definition and fill the corresponding task structures to the BAPI, a task gets created at the phase level. But when I pass the GUID of the task along with the task
information, subtask does not get created. The BAPI returns the following error message:
DPR_SHARED 051: You cannot create Task for (Task Name).
Steps for recreating the error message are:
1. GUID is found out using function module CONVERSION_EXIT_DPRCE_INPUT.
2. GUID and task information is passed to BAPI_BUS2175_CREATE.
3. Task is created if project definition GUID is passed, but if task GUID is passed, there is no subtask created. An error message is displayed:
DPR_SHARED 051: You cannot create Task for (Task Name).
Any help would be appreciated.
Thanks,
Tom

Hi all,
I have used the same and it works absolutely fine.
here is a code sample
CONSTANTS:
   lc_rfc_none        TYPE string VALUE 'NONE'.       " RFC on same server
DATA:
  lv_header_task_guid TYPE bapi_ts_guid-parent_guid, " Header Task GUID
  ls_sub_task TYPE bapi_ts_task,
  ls_sub_task_upd TYPE bapi_ts_task_upd,
  lt_crtask_return TYPE TABLE OF bapiret2,
  ls_extension_in TYPE bapiparex,
  ls_extension_out TYPE bapiparex,
  lv_task_guid TYPE bapi_ts_guid-parent_guid. " Task GUID
* Assign sub-task name. (Task Number is internally generated)
ls_sub_task-task_name = 'ST 1.1'.
ls_sub_task_upd-task_name = 'X'.
* Assign Sort Number
ls_sub_task-sort_number = '00010'.
ls_sub_task_upd-sort_number = 'X'.
* Assign Duration
ls_sub_task-duration = 30.
ls_sub_task_upd-duration = 'X'.
* Assign Work.
ls_sub_task-planned_work = 240.
CALL FUNCTION 'CONVERSION_EXIT_CUNIT_INPUT'
  EXPORTING
    input          = 'H'
  IMPORTING
    output         = ls_sub_task-planned_work_unit
  EXCEPTIONS
    unit_not_found = 1
    OTHERS         = 2.
IF sy-subrc <> 0.
ENDIF.
ls_sub_task_upd-planned_work = 'X'.
ls_sub_task_upd-planned_work_unit = 'X'.
CALL FUNCTION 'BAPI_BUS2175_CREATE'
     DESTINATION lc_rfc_none
     EXPORTING
         iv_parent_guid   = lv_header_task_guid
         is_task          = ls_sub_task
         is_task_upd      = ls_sub_task_upd
         is_extension_in  = ls_extension_in
      IMPORTING
         es_extension_out = ls_extension_out
     TABLES
         return           = lt_crtask_return.
* If task is successfully created,
READ TABLE lt_crtask_return WITH KEY type = lc_success number = '114'.
IF sy-subrc = 0.
* Get task GUID
lv_task_guid = lt_crtask_return-message_v1.
CALL FUNCTION 'BAPI_CPROJECTS_COMMIT_WORK'
  DESTINATION
    lc_rfc_none
  TABLES
    return = lt_bapiret2.
endif.
In order to find the GUID of the header task use function module:
DPR_GET_GUID_BY_ID_FROM_DB
with IV_Number  = task number for the header task and IV_OBJECT_TYPE = TTO
Read the documentation for 'BAPI_BUS2175_CREATE' before using it.
make sure you have maintained IS_TASK_UPDATE structure as well.
