week date literal - Details

• 
  Key Concepts: 
  Week date literal is a type of ABAP literal used to represent a date in the form of a week number and year. It is used to represent a date in the form of a week number and year, such as '2020W01'. This type of literal is used in the ABAP Runtime Environment (BC-ABA) to store and manipulate dates. 
  
  How to use it: 
  Week date literals can be used in ABAP programs to store and manipulate dates. To use a week date literal, you must first declare it as a data object. This can be done using the following syntax: DATA: lv_week_date TYPE wdyyyymmdd. Once declared, you can assign a value to the data object using the following syntax: lv_week_date = '2020W01'. 
  
  Tips & Tricks: 
  When using week date literals, it is important to remember that they are stored as strings and not as dates. Therefore, when manipulating them, you must use string functions instead of date functions. Additionally, when comparing two week date literals, you must use string comparison functions instead of date comparison functions.
