Error AM010 , OX09 ADRC EKPO-ADRN2

Hi Experts:

Address for storage location has been deleted by OX09.

As far as I know( also tested), even the address was deleted, the address master itselft still exist in ADRC table.

Now I found that the address number is missing in ADRC table, and due to this, all existing STO documents with this

address number in EKPO-ADRN2 have AM010 error.

And follow-on documents of these STO(e.g. delivery billing) is missing ship-to party address.

(* when create STO, the storage location address number will be automatically saved in EKPO-ADRN2)

Questions:

1, How to fix this?

2, Anyway to trace why the address was removed from ADRC table?

Many thanks in advance.
