HR_INITIALIZE_BUFFER, HR_PSBUFFER_INITIALITZE

[Former Member]

Hi,

i want to use HR_INFOTYPE_OPERATION to modify infotype 0008.

I have found some examples that use this function modules to modify infotypes:

CALL FUNCTION 'BAPI_EMPLOYEE_ENQUEUE'

EXPORTING

NUMBER = PERNR

IMPORTING

RETURN = BAPI_RETURN.

CALL FUNCTION HR_INITIALIZE_BUFFER.

CALL FUNCTION 'HR_PSBUFFER_INITIALIZE'.

CALL FUNCTION 'HR_INFOTYPE_OPERATION'

EXPORTING

...

CALL FUNCTION 'BAPI_EMPLOYEE_DEQUEUE'

EXPORTING

NUMBER = PERNR

IMPORTING

RETURN = BAPI_RETURN.

I understand what this function modules do:

- BAPI_EMPLOYEE_ENQUEUE

- BAPI_EMPLOYEE_DEQUEUE

- HR_INFOTYPE_OPERATION

But i don't know what this other functions do:

- HR_INITIALIZE_BUFFER

- HR_PSBUFFER_INITIALIZE

I have tried to find info in internet, but it's been frustrating. It seems everybody use this functions without knowing what they do.

Can anyone help me?

Thanks.

these FM' s initializes Buffer ... means it clears ..

Obviously, i know they clear buffers. But, what are this buffers for?

Are this functions necessary to use HR_INFOTYPE_OPERATION? If i use them, what impact do they have?
