CY177 - Details

• The SAP error message CY177, which states "Please select one combination," typically occurs in the context of SAP's Controlling (CO) module, particularly when dealing with cost center accounting or internal orders. This error usually arises when the system expects a single combination of parameters (like cost center, order, or activity type) to be selected, but multiple or no combinations are provided.
  
  Cause:
  
  Multiple Selections: The user may have selected multiple cost centers, orders, or other parameters when the system requires only one.
  No Selection: The user may not have selected any combination at all, leading to the error.
  Incorrect Configuration: There may be issues with the configuration of the controlling area or the settings related to the specific transaction being executed.
  
  
  Solution:
  
  Single Selection: Ensure that you are selecting only one combination of the required parameters. For example, if you are working with cost centers, select only one cost center at a time.
