Documentation
Definition
A lock object is a virtual link of several SAP tables which is used to synchronize simultaneous access by two users to the same set of data (SAP lock concept).
Locks are requested and released in the programming of online transactions by calling certain function modules which are automatically generated from the definition of the lock objects. These lock objects must be explicitly created in the ABAP Dictionary.
To set locks, you must perform the following steps:
- You must define a lock object in the ABAP Dictionary. The name of the lock object should begin with E.
- The function modules for requesting and releasing locks which are created automatically when the lock object is activated must be linked to the programming of the relevant online transactions.
Please note the following input conventions when using character strings in a search.
char
All characters (apart from those mentioned below) stand for themselves, with no distinction made between upper and lower case. Upper and lower case are distinguished in text fields, such as short descriptions.
*
denotes any character string.
+
denotes exactly one character.
<>
denotes negation (applies if the specified character string does not match).
$
tests for a blank field (entering <>$ means that the system searches for all fields containing at least one character).
>
greater than.
<
less than.
&
logical AND (intersection), followed by the next character string without blanks.
or/
logical OR (union), followed by the next character string without blanks.
Priority starts at the top, i.e. & is evaluated before , but after *.
