ABAP Program to upload accrual object using ACAC_OBJECT_MODIFY_EXT

I have a requirement to develop an RFC to call the ACAC_OBJECT_MODIFY_EXT function module for accrual upload. I have created the BAPI / ALE interface for it to be used in LSMW. However the program returns a DUMP when calling the function module because of the parameter passed. I need help with this. A program using this function module would do it for me.

Here is the interface for the FM

CALL FUNCTION 'ACAC_OBJECT_MODIFY_EXT' "

* EXPORTING

* is_assignments = " ace_assignments

* it_accounts = " aceds_accounts_t

* it_params = " aceds_param_t

* id_effdate = " ace_effdate

* is_post_params = " aceps_manual_posting_params

* id_testrun = 'X' " ace_testrun

IMPORTING

ed_data_created = " flag

ed_data_changed = " flag

et_docitems = " aceps_ace_doc_extended_t

et_return = " bapiret2_t

et_accdoc_return = " ace_accdoc_return_t

CHANGING

cs_object = " acac_object_header_ext

ct_object_items = " aceds_items_t

.

Typical error:

An exception occurred that is explained in detail below.

The exception, which is assigned to class 'CX_SY_DYN_CALL_ILLEGAL_TYPE', was

not caught in

procedure "ZBAPIACCRUALUPLOAD" "(FUNCTION)", nor was it propagated by a RAISING

clause.

Since the caller of the procedure could not have anticipated that the

exception would occur, the current program is terminated.

The reason for the exception is:

The call to the function module "ACAC_OBJECT_MODIFY_EXT" is incorrect:

The function module interface allows you to specify only

fields of a particular type under "IT_ACCOUNTS".

The field "ACCOUNTS" specified here is a different

field type

.

Attached to the file is the source code of the rfc i am trying to create( ZBAPIACCRUALUPLOAD)
