TU180 - Details

• The SAP error message TU180, which states "You cannot enter months as period length," typically occurs when you are trying to define a period length in a transaction or configuration that does not accept months as a valid unit of time. This error is often encountered in the context of financial or controlling modules where period lengths are expected to be defined in days, weeks, or years, rather than months.
  
  Cause:
  
  Incorrect Period Length Specification: The most common cause of this error is that the system is expecting a different unit of time (like days or weeks) but you have entered "months" as the period length.
  Configuration Settings: The configuration settings in the relevant module (like Financial Accounting, Controlling, etc.) may not support monthly periods for the specific transaction or report you are trying to execute.
  Transaction Context: The specific transaction or report you are using may not be designed to handle monthly periods,
