P&L lock - Details

• 
  Key Concepts: 
  P&L lock is a feature in SAP Financial Accounting (FI-GL-GL Basic Functions) that prevents users from posting to a Profit and Loss (P&L) account. This feature is used to protect the integrity of the P&L account and ensure that all postings are accurate and up-to-date.
  
  How to use it: 
  To enable the P&L lock, go to the Financial Accounting (FI) module in SAP and select the “P&L Lock” option. This will open a window where you can select the P&L accounts you want to lock. Once you have selected the accounts, click “Save” to activate the lock. 
  
  Tips & Tricks: 
  When using the P&L lock, it is important to remember that it only applies to postings made directly to the P&L account. If a posting is made to another account that affects the P&L account, such as an expense or revenue account, then the P&L lock will not apply.
