In SAP S/4HANA FI, tolerance groups (transaction OBA4) are used to set posting limits for different types of transactions. Let's understand using two amounts:
1. "$1000 for Amount per document":
- This refers to G/L (General Ledger) postings
- It means users can post G/L account transactions up to $1000 without requiring additional approval
- These are direct postings to G/L accounts (like expense accounts, revenue accounts, etc.)
2. "$2000 for Amount per open item account item":
- This refers to postings to open item managed accounts, which includes both A/P (Accounts Payable) and A/R (Accounts Receivable)
- This $2000 limit would actually apply to both A/P and A/R accounts since both are open item managed accounts
- G/L postings are direct transactions that need to be controlled separately from subledger postings
The difference between G/L (direct) postings and subledger postings:
G/L Direct Postings:
- These are transactions posted directly to G/L accounts without involving a subledger
- Examples:
* Recording office supplies expense directly to an expense account
* Recording bank charges directly to a bank charges account
* Recording a manual journal entry between two G/L accounts
- These are typically more "sensitive" because:
1. They bypass the additional controls that come with subledger processing
2. There's no supporting subledger detail to validate against
3. They're often manual entries rather than system-generated
Subledger Postings (like A/P and A/R):
- These transactions first go through a subledger (like Vendor or Customer master records)
- They have additional built-in controls:
1. They require valid master data (vendor/customer numbers)
2. They create audit trails in both the subledger and G/L
3. They often follow predefined business processes (like purchase-to-pay cycle)
- Examples:
* Recording a vendor invoice (A/P)
* Recording a customer payment (A/R)
This is why in OBA4:
- The $1000 limit for direct G/L postings is lower than the $2000 limit for subledger postings
- It's a common control practice to set stricter limits on direct G/L postings because they have fewer inherent controls
- The higher limit ($2000) for subledger transactions reflects the additional control layers already present in subledger processing
Would you like me to explain more about how these tolerance groups work in practice?
