Problem with CO-PA table structures and check table

Hi Gurus!

I created a custom table ZMDCM_PLNLVLCHK with three fields ZZPLC PLCDESC and EPSC. By mistake the second field PLCDESC is marked as a primary key. I have saved and activated the table.

Now this first field ZZPLC is inserted in many standard table as an append structure. This field also uses my custom table ZMDCM_PLNLVLCHK as a check table in many standard tables.

Now when I try to remove the primary key of field PLCDESC it does not allow me to do so because this custom table is already used as a check table. Now I need to remove the check table relation ship of this field with standard table before removing primary key from the custom table.

What is the transaction or configuration thru which these structures

CE01000

CE71000

CE81000

KOMKAKE

ZFIAP_A_PLI

ZOXD100019

ZOXD100021 CO-PA

and data base tables

CE11000

CE21000

CE41000

CE41000_ACCT

CE41000_KENC

are being created. Is there a way to go and remove check table from these above standard CO-PA structures and tables.

Thanks & Regards

Ramachandran Babu
