BDC or HR_INFOTYPE_OPERATION

Hi All,

doing some research on the relative adv's/disadv's of using either HR_INFOTYPE_OPERATION or BDC on transaction PA30 to upload file data into corresponding infotypes.

so far i found that:

1. HR_INFOTYPE_OPERATION must be confined to small amounts of data as it uses a CALL DIALOG approach and we may even run out of buffer memory.

2. HR_INFOTYPE_OPERATION takes less amount of time when compared with BDC

3.programming will be easy when the fm HR_INFOTYPE_OPERATION is used.

It would be great if some of u can add few more points to the list viz.,

1.what happens if, if there are any custom fields in the infotype?

2.what happens if the country grouping changes?

i would be more than happy if some of u can provide me related links/threads to explore.

reward guaranteed
