TT015 - Details

• The SAP error message TT015, "The Occurs parameter in a loop must be at least 1," typically occurs in ABAP programming when you are defining an internal table with a loop statement, and the OCCURS parameter is set to a value less than 1. This error is related to the definition of internal tables in older versions of ABAP, particularly when using the TABLES keyword.
  
  Cause:
  
  Incorrect OCCURS Value: The OCCURS parameter specifies the initial size of the internal table. If it is set to 0 or a negative number, the system will raise this error.
  Legacy Code: This error is more common in legacy ABAP code that uses the older syntax for defining internal tables, which is less common in modern ABAP programming.
  
  
  Solution:
  
  
  Check the OCCURS Parameter: Ensure that the OCCURS parameter in your internal table definition is set to at least 1. For example:
  DATA: BEGIN OF itab OCCURS 10,
