Few instances of P_ORGIN are missing VDSK1 field

Hi Experts,

In our landscape, we have converted VDSK1 (Org Key) to Org Field. There are a few instances of P_ORGIN where i cannot find VDSK1 field. Also, i checked in AGR_1251 & 1252 tables, the values are missing in tables as well.

Have you experienced it in your past / current work. What could be the reason?

Thanks, Vishwas
