GU303 - Details

• The SAP error message GU303 ("Objects with leading zero may not be deleted") typically occurs when you attempt to delete a master data object (like a material, customer, or vendor) that has a leading zero in its identifier. This is a common issue in SAP systems, especially when dealing with number ranges and object identifiers.
  
  Cause:
  
  Leading Zeros in Identifiers: The error arises because SAP treats identifiers with leading zeros differently. For example, if you have a material number like "00012345", SAP may not allow you to delete it due to the way it manages these identifiers.
  Data Integrity Rules: SAP has built-in data integrity rules that prevent the deletion of certain objects to maintain the consistency of the database. Objects with leading zeros are often considered critical and cannot be deleted directly.
  
  
  Solution:
  
  Check Object Status: Before attempting to delete, ensure that the object is not being used in any transactions or linked to
