How are postings maintained in Parallel Accounting?

 Postings in Parallel Accounting are maintained by recording financial transactions in each parallel ledger separately, ensuring that the appropriate accounting rules and principles are applied to each ledger.

Great — this question is about how postings actually behave in parallel accounting. This is practical knowledge.


How Are Postings Maintained in Parallel Accounting?

Key idea:

👉 You do NOT post twice.
👉 You post once.
👉 SAP updates multiple ledgers automatically.

This is the whole power of the ledger approach.


What Happens When You Post a Journal Entry?

Example entry:

Dr Expense
Cr Bank

When you post this in SAP:

LedgerWhat Happens
0L (Leading)Posting created automatically
L1 (Non-leading)Posting also created automatically

So one transaction → multiple ledgers updated.

This is called:

👉 Real-time parallel posting


Why SAP Does This

Because business does NOT want:

  • Duplicate entries

  • Multiple systems

  • Manual reconciliation

SAP ensures consistency across ledgers.


Important Detail Most People Miss

There are two types of postings in parallel accounting:

1️⃣ Ledger-Group Posting (Automatic)

Normal postings go to:

  • Leading ledger

  • All relevant non-leading ledgers

Example:
Vendor invoice → posts everywhere.


2️⃣ Ledger-Specific Posting (Adjustment)

Sometimes differences exist between GAAPs.

Example:
US GAAP requires extra depreciation.

You post adjustment only to L1 ledger.

This is called:
👉 Ledger-specific posting.

This is advanced but very important.


Summary

Posting TypeWhere Posted
Normal business transactionAll ledgers
GAAP adjustmentSpecific ledger only

This is how SAP maintains parallel accounting.
