Error while creation of service entry via BAPI_ENTRYSHEET_CREATE

Question

Hi All,
I am struggling while creation of service entry using the BAPI, BAPI_ENTRYSHEET_CREATE. I am getting error ""No account assignment exists for service line 0000000010". I am passing the essr, eskn,eskl, esll structures as-
Please help sorting out what is the issue in the parameters, I am able to manually create an SER via ML81N though.

The issue resolved now by passing the following parameters-
EntrySheet header-
BAPI_ESSR-PO_NUMBER = PO_NUMBER.
BAPI_ESSR-PO_ITEM   = PO_ITEM.
BAPI_ESSR-SHORT_TEXT = as entered by user
BAPI_ESSR-ACCEPTANCE = u2018Xu2019 or space.
BAPI_ESSR-DOC_DATE = Todayu2019s date.
BAPI_ESSR-POST_DATE = Todayu2019s date.
BAPI_ESSR-PCKG_NO = '0000000001'.
Entry Sheet Account Assignment-
BAPI_ESKN-COSTCENTER = Cost Center
BAPI_ESKN-WBS_ELEMENT = WBS element
BAPI_ESKN-AUFNR = Order
Entry Sheet Services-
Unplanned line-
BAPI_ESLL-PCKG_NO = '0000000001'.
BAPI_ESLL-LINE_NO = LINE_NO (000001).
BAPI_ESLL-EXT_LINE = '0000000000'.
BAPI_ESLL-OUTL_LEVEL = 0.
BAPI_ESLL-OUTL_IND = 'X'.
BAPI_ESLL-SUBPCKG_NO = '0000000002'.
Planned line-
  BAPI_ESLL-LINE_NO = LINE_NO (000002).
  BAPI_ESLL-PCKG_NO = '0000000002'.
  BAPI_ESLL-SUBPCKG_NO = '0000000000'.
  BAPI_ESLL-EXT_LINE =   '0000000010'.
  BAPI_ESLL-SERVICE = '0000000000'.
  BAPI_ESLL-OUTL_LEVEL = 0.
  BAPI_ESLL-OUTL_IND = ' '.
  BAPI_ESLL-QUANTITY = as entered by user
  BAPI_ESLL-BASE_UOM = PO_SERVICES-BASE_UOM.
  BAPI_ESLL-GR_PRICE = as entered by user
  BAPI_ESLL-PLN_PCKG = '0000000000'.
  BAPI_ESLL-PLN_LINE = '0000000001'.
Entry Sheet Service access values-
BAPI_ESKL-LINE_NO = '2'.
BAPI_ESKL-PCKG_NO = '0000000002'.
BAPI_ESKL-PERCENTAGE = '100'.
Thankyou!
