BPC 7.5 Installation Guide - Clarification Needed on UJA_SVR_DEFAULT

Question

Page 23, Section 3.4 Item number 10 of the BPC 7.5 NetWeaver Installation Guide says to do the following:
2. Go to transaction SE38 and run program UJA3_WRITE_SYS_USERS.
This updates the settings in table UJA_SVR_DEFAULT with the Planning and Consolidation users defined earlier (step 2).
3.Assign a single domain user to each user type:
Planning and Consolidation System Administrator User - Enter <Domain>\<user name> in AD mode, or <CMS enterprise name> in CMS mode
Planning and Consolidation Administration User - Enter <Domain>\<user name> in AD mode, or <CMS enterprise name> in CMS mode
Planning and Consolidation User - Enter <Domain>\<user name> in AD mode, or <CMS enterprise name> in CMS mode
If I use UJA_WRITE_SYS_USERS and then go in and assign a domain user for each user type, won't this overwrite what UJS_WRITE_SYS_USERS has updated? What would be the purpose of the defining AD users in this table? The .NET server install for BPC only needs the domain account for BPC Sys Admin, and the three ABAP users for BPC Sys Admin, BPC Admin, and BPC User.
My question is why do you need to "Assign a single domain user to each user type"?
Thanks in advance!

Answer 1

I am not sure that you have answered my question. Let me try to add more detail.
No where in the installation do you enter the passwords for the <domain\Admin> or <domain\User> domain user accounts. In fact the installation guide only asks for the following in section 3.4:
6. Enter the System Administrator ID and password for the Windows Server that you are logged on to, then select Next.
11. Enter the System Administrator, Administrator, and User user IDs, together with their passwords, for the ABAP service users that were created during the ABAP server component configuration. For more information, see Configuring the ABAP Server Component [page 20].
So again, my question is why do you need to specify the <domain\Admin> and <domain\User> accounts in the UJA_SVR_DEFAULT table in NetWeaver?
Thanks,
