We cannot create adjustment only elements in Oracle Payroll.

API = pay_element_entry_api.create_element_entry
Package Name = pay_element_entry_api
File Name = pyeleapi.pkh
Business Process = create_element_entry
API's versions:
$Header: pyeleapi.pkb 115.27 2007/11/16 13:14:24 ayegappa ship $
PAY_ELEMENT_ENTRY_API

PAY_ELEMENT_ENTRY_API

We now cannot create element entries for Adjustment only elements using the API pay_element_entry_api.create_element_entry with the p_entry_type input parameter = 'E'.
Error produced is:
" ORA-20001 : These element entries are not valid for an Adjustment Only element.
Cause: Either the entry type is incorrect, or the adjustment entry is not defined.
Solution: Supply an entry type that is in 'A','R' or 'B',and ensure that the target_entry_id (for A or R type) or original_entry_id (for B type) parameter is not null."
Steps to Reproduce:
Use pay_element_entry_api.create_element_entry to create an Adjustment Only element with p_entry_type='E'

---> The API is called from package code within the custom library form, the pl/sql block looks like:

begin

pay_element_entry_api.create_element_entry

(p_validate

=> false

,p_effective_date

=> ld_paaf_eff_start_date

,p_business_group_id

=> ln_business_group_id

,p_assignment_id

=> p_assignment_id

,p_element_link_id

=> ln_cost_element_link_id

,p_entry_type

=> 'E'

,p_input_value_id1

=> ln_cost_input_value_id

,p_entry_value1

=> ln_cost_balance_value

,p_effective_start_date => ld_ee_effective_start_date

,p_effective_end_date

=> ld_ee_effective_end_date

,p_element_entry_id

=> ln_ee_element_entry_id

,p_object_version_number => ln_ee_object_version_number

,p_create_warning

=> lb_ee_create_warning);

exception

when others then
omhr_log_msg('OMPAY_LEGAL_ENTITY_TRANSFER','Create adj element error for person_id '||ln_person_id||' and element name: '||c_let_default_elements.element_name,SQLERRM);
