Content Server 6.40 - How to know where documents came from?

Hi All,

I have very little knowledge of Content Server or how it's configured with a SAP system.

What I need to know is how do I find out where each document stored in the MaxDB database originates.

I know on our system, some come from ArchiveLink and some from Business Document Store.

I know this because having run program DMS_KPRO_CHECK1, it states that

PHIOS in Content Server w/o Reference in KPRO

Number of PHIOS: 480680

Now I know in Content Server table DOCUMENT0001 in MaxDB there are 4.2 million records and the above 480 thousand are from the BDS table BDSPIO6 with Content Category of Z2 our defined Content Repository.

I also know that in table TOA01 I have 1.6 million records against Z2 repository.

So how am I supposed to find where all these documents originated?

Thanks

Craig
