  The SAP error message M2099, which states "Enter period in the format YYYY/__," typically occurs when a user is trying to enter a period in a transaction or report, but the format of the period is incorrect. This error is common in modules that deal with materials management, inventory, or financial postings.
  
  Cause:
  The error is caused by the user entering a period in an incorrect format. SAP expects the period to be entered in the format of "YYYY/MM," where:
  
  YYYY represents the four-digit year.
  MM represents the two-digit month (01 for January, 02 for February, etc.).
  
  If the user enters the period in any other format (e.g., "2023-01" or "2023/1"), SAP will not recognize it and will throw the M2099 error.
  
  Solution:
  To resolve this error, follow these steps:
  
  
  Check the Format: Ensure that you are entering the period in the correct format: YYYY/MM. For example, if you want to enter January 2023, you should enter 2023/01.
