What is lock collision in SAP BC-CST-EQ - Enqueue?

SAP Term: lock collision

• Component: BC-CST-EQ

• Component Name: Enqueue

• Description: A lock situation where the enqueue server rejects a requested lock since another ABAP user has already been granted write access to the lock object. If an ABAP user has set an exclusive E lock, a lock collision occurs whenever another ABAP user requests read or write access to the lock object. If an ABAP user has set an exclusive not cumulative X lock, a lock collision occurs whenever that same user again or another ABAP user requests read or write access to the lock object.

• Key Concepts: 
  Lock collision is a situation that occurs when two or more users attempt to access the same data record at the same time. This can lead to data inconsistency and corruption. In SAP, lock collisions are managed by the BC-CST-EQ Enqueue component. 
  
  How to use it: 
  The BC-CST-EQ Enqueue component is used to manage lock collisions in SAP. It works by assigning a unique lock to each user who attempts to access a data record. If two users attempt to access the same record at the same time, the Enqueue component will detect this and prevent both users from accessing the record until one of them releases their lock. 
  
  Tips & Tricks: 
  When using the BC-CST-EQ Enqueue component, it is important to ensure that all locks are released as soon as possible. This will help prevent unnecessary delays and ensure that data remains consistent and up-to-date.
