• What is the cause and solution for SAP error message ABAP_TESTDOUBLE012 - &4 Setting of values not allowed as iterator is active ?

  The SAP error message ABAP_TESTDOUBLE012 with the text "Setting of values not allowed as iterator is active" typically occurs in ABAP programs when you attempt to modify a table or internal table while an iterator is active. This is a common issue when using loops or iterators to process data.
  
  Cause:
  The error arises because the ABAP runtime environment does not allow modifications to the internal table while it is being iterated over. This is to prevent inconsistencies and unexpected behavior during the iteration process. The iterator maintains a pointer to the current position in the table, and changing the table while iterating can lead to errors or undefined behavior.
  
  Solution:
  To resolve this error, you can follow these approaches:
  
  
  Avoid Modifying the Table During Iteration:
  
  If you need to modify the table, consider collecting the changes in a separate internal table or a list and apply those changes after the iteration is complete.
