Client Administration

When importing a table snapshot, what does 'Import Only Tables' deliberately skip, and when is that dangerous?

You run SCC5N to delete a client. When should you LEAVE 'Delete from System Table T000' unchecked, and what does ticking it cost you?

The old local client copy forced a 'ghost logon' into the target client. What was the risk, and how does SCCLN remove it?

When is a client's logical system optional, and when does its absence actually break something?

You find client 001 in an S/4HANA system migrated from SAP ERP. What is it, and what must you verify before deleting it?

What is the near-universal naming convention for a logical system?

You want a change audit trail, so you consider setting the Log Changes flag on your busiest tables. Which tables must you NOT do this for, and why is the flag riskier than a local toggle?

Looking at a client export's transport requests, how do you tell the client-dependent data request from the cross-client customizing one by name alone?

Client transport is widely disliked yet sometimes unavoidable. What single condition justifies it, and what cost do you accept?

A user created in client 100 can't log into client 200. A colleague calls it a bug. Why is it expected, and what does it force at provisioning time?

The flag 'Protection against SAP Upgrade' sounds like something you'd want on an important client. Why is setting it almost always a mistake?

When you export a client with SCC8N, which cross-client data can ride along — and which is impossible to include?

For a training client you recreate weekly from the same source, why is re-exporting a table snapshot far cheaper than the first export — and what makes that NOT true on a busy source?

Table change logs are filling the database. When do you archive them (BC_DBLOG via SARA) versus delete them (RSTBPDEL)?

A colleague wants to maintain a different RFC destination per client. Why is that impossible, and what's the gotcha when one team edits it?

A hardening checklist tells you to secure client 066. On a current S/4HANA system, what's wrong with that instruction?

You set rec/client = ALL to start table logging but nothing is being logged. What did you forget, and what forces you to ALL instead of a client list?

Why must application users never get access to client 000, and why is it a bad place to experiment even though it looks bare?

SCC4 opens display-only even though you have full authorization. Why, and what must you confirm before creating a client?

You imported a client transport with STMS into the target client. The data is there but inconsistencies remain. What step did you most likely skip?

SCC1N refuses to write into your production client. What is it actually copying, and which setting overrides the block — at what risk?

You change an ABAP program in client 100 to fix a problem there only. Why does client 200 see the change too, and how do you actually isolate behavior per client?

Across local, remote, and client-transport copies, what single landscape condition pushes you from a remote copy down to a client transport?

What roles can a client be assigned in SCC4?

In SCC4 a golden (customizing) client and a production client look similar. Which single setting must differ between them, and what breaks if you copy production's lock onto the golden client?

Before you can assign a logical system in SCC4, where must it already exist — and what client constraint applies?

Both a golden client and a sandbox client are non-production. Which one do you experiment freely in, and what's the cost of mixing them up?

Among the four 'Changes and Transport for Client-Specific Objects' options, which fits a sandbox where changes must NEVER leave the system — and why isn't 'No Changes Allowed' the answer?

Where are SCC4 client settings stored, and why don't you need to turn on table logging to audit changes to them?

You must copy FROM a live production source client. Which two settings protect consistency, and which one validates the run without touching the database?

At the Dictionary level, what precisely makes a table client-dependent — not just 'it has a MANDT field'?

Why must 'Release Transports on Export' be enabled for a client export, instead of releasing the request later in SE09/SE01?

When you evaluate a table change log in SCU3, what does each entry actually show — and what's the gotcha when reading it?

As of S/4HANA 1909 (SAP BASIS 7.54) the client copy tool got much faster. What makes it faster, and roughly how much for a local copy?

A remote client copy (SCC9N) will span systems on different release/structure levels. Which option do you set, and how is the source defined?

Before a client copy you check size in SCC_CLIENT_SIZE. Which delivery class usually dominates, and how does that change your copy plan?

An Open SQL SELECT on a client-dependent table has no client filter in the code, yet returns only the logon client's rows. What does that for you, and where does it NOT apply?

A teammate assumes all customizing is client-dependent and will copy with the client. Where does that assumption fail, and what goes missing?

Your transport of a cross-client customizing change won't originate from the client. Which SCC4 setting likely blocks it, and what values can it take?

SCC_COMPARE offers a checksum comparison and a detailed comparison. You need to know WHICH records differ between two clients — which mode, and what does the other one only tell you?

A client copy ran far longer than expected. Which transaction and which tab tell you which tables dominated the runtime?

You set the Log Changes flag on a customizing table but no changes are being recorded. What second condition is required?

How is a client identified, and what's wrong with assuming a freshly installed S/4HANA system already has 000, 001 and 066?

You're refreshing a QA client and want fresh customizing plus the existing users kept — but NOT production master/transaction data. Which copy profile, and which one would you wrongly grab?

Table snapshots are pitched as a more convenient alternative to client transports. When do they help, and in which case can they NOT replace a client transport?

You want a client that can serve as a copy SOURCE and be compared, but can never be overwritten. Which Copy/Comparison Tool protection level — and how does it differ from level 2?

You created a client in SCC4 but it has no users and no data. Why isn't SCC4 enough, and what actually populates it?

A colleague still starts local client copies with SCCL and always has to activate SAP* on the target client first. What does the S/4HANA successor transaction change?

Instead of writing client-export data to transport files on disk, S/4HANA offers snapshot containers. How do they move the data and what's the payoff?

During SAP Best Practices prep on S/4HANA, which single table entry decides whether the copy program pulls all client-000 reference settings or only the whitelisted ones?

You activated SAP Best Practices with demo data in your sandbox, transported the result to the next client, and the sample data vanished. Why?

Your S/4HANA system has a brand-new client with no user master record, and you need to log on as the emergency SAP* user. Why won't the old profile-parameter trick work anymore, and what do you do instead?

You're following a 2023 runbook that calls SCCL, SCC9, SCC5, SCC8, SCC7 and SCC1 for client operations. What changed with S/4HANA's new HANA-based client tools?

Before a large client copy on S/4HANA you want to confirm HANA has enough memory headroom, and later compare two clients. Which new helper transactions cover this?

You're setting up a client to activate SAP Best Practices and must pick between a Best Practices Client and a Merged Client. Why is this a choice you can't walk back?

Before the modern dpmon method, how did admins activate SAP* in a fresh client, and why did that procedure require two system restarts?
