• What is the cause and solution for SAP error message FDT_EXPRESSIONS580 - Loop mode does not allow to define the number of repeats ?

  The SAP error message FDT_EXPRESSIONS580 indicates that there is an issue with the configuration of a loop mode in a form or a data processing scenario within SAP's Form Data Tool (FDT). Specifically, this error occurs when you attempt to define the number of repeats for a loop mode, which is not allowed.
  Cause:
  The error arises because:
  
  In loop mode, the system is designed to process data in a continuous loop without a predefined number of iterations. Therefore, specifying a number of repeats contradicts the nature of loop mode.
  This typically happens when you are trying to set properties or configurations that are not compatible with the loop mode settings.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Loop Mode Configuration:
  
  Review the configuration of the loop mode in your form or data processing setup. Ensure that you are not trying to set a repeat count for a loop mode.
  
  
  
  Remove Repeat Count:
  
  If you have defined a number of repeats in the properties of the loop, remove that definition. Loop mode should be set to process data without a fixed number of iterations.
  
  
  
  Review Documentation:
  
  Consult the SAP documentation or help resources related to the Form Data Tool and loop mode configurations. This can provide insights into the correct setup and usage.
  
  
  
  Test Changes:
  
  After making the necessary adjustments, test the form or data processing scenario to ensure that the error no longer occurs and that the loop functions as intended.
  
  
  
  Seek Help from SAP Support:
  
  If you are unable to resolve the issue, consider reaching out to SAP support or consulting with a colleague who has experience with FDT configurations.
