• What is the cause and solution for SAP error message FSCY106 - Substring cannot be created; only &1 substrings are permitted ?

  The SAP error message FSCY106 indicates that there is an issue with the number of substrings being created in a certain context, typically related to the use of string manipulation functions or data structures that have a limit on the number of substrings they can handle. The message states that only a specified number of substrings (denoted by &1) are permitted, and the operation you are trying to perform exceeds this limit.
  Cause:
  
  Exceeding Substring Limit: The primary cause of this error is that the operation you are attempting to perform is trying to create more substrings than the allowed limit. This can happen in various scenarios, such as when processing strings in a report, program, or function module.
  Data Structure Limitations: Certain data structures or configurations in SAP may have predefined limits on the number of substrings they can handle, leading to this error when those limits are exceeded.
  
  Solution:
  
  Review the Code: Check the code or configuration where the error occurs. Look for any string manipulation functions or operations that are creating substrings. Ensure that the number of substrings being created does not exceed the allowed limit.
  Optimize String Handling: If possible, optimize the way strings are being handled. This may involve reducing the number of substrings created or consolidating data to fit within the limits.
  Increase Limits (if applicable): If you have control over the data structure or configuration, consider increasing the limit on the number of substrings if it is feasible and does not impact system performance or stability.
  Error Handling: Implement error handling in your code to manage situations where the limit might be exceeded, providing a fallback or alternative processing path.
