• What is the cause and solution for SAP error message WM181 - Starting date before start of validity period of material & ?

  The SAP error message WM181 ("Starting date before start of validity period of material") typically occurs in the Warehouse Management (WM) module when you attempt to perform an operation (like stock transfer, picking, or inventory management) involving a material that has a defined validity period, and the date you are trying to use is outside of that period.
  Cause:
  
  Validity Period Not Set Correctly: The material may have a validity period defined in its master data, and the date you are trying to use is before the start date of this validity period.
  Incorrect Date Entry: The date you are entering for the transaction may be incorrect or not aligned with the material's validity period.

  Solution:
  
  
  Check Material Master Data:
