PO13 and 0001 infotype (HR_INFOTYPE_OPERATION + badi HRBAS00INFTY

Question

Hello Friends,
We have cretaed a position description subtype and assigned it to 1002 infotype.
Query: 1) Adding 2 customer fields(Subtype and description) to infotype 0001 (This is done using PM01).
2) Using Po13, they assign a subtype(position description) for a particular Position.
Now the requirement is When they assign subtype to a postion in PO13 and save then these subtype
and subtype description should be stored in 0001 infotype.
the position should use to locate the employee and once the employee have been located update 0001.
for ths I have implemented a PO13 badi HRBAS00INFTY(IN updating method) and inside the BADI we are calling
HR_INFOTYPE_OPERATION' to update the eMPLOYEE(0001 INFOTYPE).
Problem: Now the problem is , when we open PO13 in change mode to assign a subtype to Position ,sap creates a lock entry and when svae we are call
HR_INFOTYPE_OPERATION' to update the eMPLOYEE(0001 INFOTYPE).but HR_INFOTYPE_OPERATION' also internally tries to lock the position but raising a
message "You have already locked object/infotype S50000024".
Pleae find below function and follwoing parameter I am suing for updating the person(0001 infotype) .
I dont understand why HR_INFOTYPE_OPERATION is trying to lock position when I pass Pernr and 0001 as a parametr.
CALL FUNCTION 'HR_INFOTYPE_OPERATION'
EXPORTING
infty = c_infty
number = wa_pernr-pernr
SUBTYPE =
OBJECTID =
lockindicator = 'X'
validityend = wa_pernr-endda
validitybegin = wa_pernr-begda
RECORDNUMBER =
record = it_0001
operation = 'MOD'
tclas = 'A'
dialog_mode = '0'
NOCOMMIT =
VIEW_IDENTIFIER =
SECONDARY_RECORD =
IMPORTING
Please help me .
Thanks In advance

Hi,
Onemore thing I couldn't find the code for IF_EX_HRBAS00INFTY-in_update.
For every BADI there will be an example interface. Here for this BADI example is IF_EX_HRBAS00INFTY. If u want to see the model code, go to SE24 and give the name :IF_EX_HRBAS00INFTY and click on display. Then you can find the methods and respective exapmle code.
One more thing
Some  BADIs will not allow calling commit work. In your BADI also already one LUW is opened, so it will not allow  to open another LUW and the respective  commit work.
Thanks and Regards,
