Why We Create Lock Objects ??

[Former Member]

Hi,

I want to know that why we create lock objects? Because in SAP when somebody is editing or working on any object then it is automatically locked.

[RaymondGiuseppi]

it is automatically locked.

is a false assertion, it is locked because in standard transaction/program the SAP developper used a lock object, start reading The SAP Lock Concept (BC-CST-EQ) and Data Consistency.

Hi Raymond,

Thanks for your quick response. One doubt is still in my mind that if SAP system is equipped with a special lock mechanism then when we will create a LOCK  OBJECT from SE11.

Thanks in Advance.

Hi,

Lock object in se11 is for custom development.

Suppose you got an object development in which you are suppose to access the same data from a table at the same time from a report/FM. To help you here you need a lock and unlock object to avoid the user getting wrong data, when one is to change data and another wants to read data for processing.

Hi Amit,

It's depends on the business applications. Some time the customized transactions/tables are very much important for the business. To control the data inconsistency need to create the locks based on the tables/fields to avoid the issues and keep the data integrity.

To add to Amit's query.

Can anyone here share their knowledge on what are the scenarios when a Standard Lock object can't be used compelling us to Create a Custom Lock Object.How Enqueue_E_table will differ from the custom lock object with Secondary tables.
