Collection Item field (INKPS) in DFKKOP table

Hi Experts,

I need some information on Collection Item Field (INKPS) in DFKKOP table.

1. What is the significance of this field?

2. This field is common between DFKKOP table and DFKKCOLLH table, So can we expect in both the tables data should be same in this field for a particular OPBEL.

Currently the issue we are facing is INKPS is always populated in DFKKCOLLH table, but for the corresponding OPBEL in DFKKOP table the INKPS field is blank.

Any idea what could be the reason?

An early response will be of great help

Thanks

Rishi
