Infotype 2007 updatation

Hi Gurus,

Could someone please help me in updating the Infotype 2007 (INS operation). I used the HR_INFOTYPE_OPERATION function module to do the same but it is not working. Its working fine for other infotypes but not for 2007.  Below is my logic.

CALL FUNCTION 'HR_INFOTYPE_OPERATION'

         EXPORTING

           infty                           = p_infty

           number                       = lv_pernr

           SUBTYPE                  = p_subty

           VALIDITYEND            = lv_desta

          VALIDITYBEGIN          = lv_deend

           record                  = p2007

           operation              = 'INS'

        IMPORTING

          RETURN                 = l_return1

          KEY                        = l_key.

Below is the error message (Dump):

The source field is too short.

In the current program "SAPLHRMM", an attempt was made to assign a field to

field symbol where the field is shorter than the type of the field

symbol. This is not supported.

It is a statement of form ASSIGN f TO <fs> CASTING... or ASSIGN f TO

<fs> with a field symbol that was created with the STRUCTURE addition.

Regards,

Siraj.
