  The SAP error message SKWF_PACKAGE012 indicates that you are trying to insert objects into a package that is not allowed. This typically occurs in the context of ABAP development when you attempt to add objects (like programs, function modules, classes, etc.) to a package that is either not modifiable or has restrictions on it.
  Causes:
  
  Package Status: The package you are trying to insert objects into may be in a non-modifiable state. This can happen if the package is a standard package delivered by SAP or if it has been set to "not modifiable" by the development team.
  Transport Layer: The transport layer associated with the package may not allow modifications. This can occur if the transport layer is set to "client-dependent" or if it is locked.
  Authorization Issues: You may not have the necessary authorizations to modify the package or to insert objects into it.
  Package Ownership: The package may be owned by another user or team, and you may not have the rights to modify it.
  
  Solutions:
  
  
  Check Package Status: 
  
  Go to transaction SE80 (Object Navigator) or SE21 (Package Builder) and check the status of the package. If it is a standard package, you will not be able to modify it.
  If it is a custom package, ensure that it is set to "modifiable."
  
  
  
  Change Package Attributes:
  
  If you have the necessary authorizations, you can change the package attributes to make it modifiable. This can be done in SE21 by selecting the package and changing its properties.

  Check Authorizations:
  
  Ensure that you have the necessary authorizations to modify the package. You may need to contact your SAP security team to verify your roles and permissions.
  
  
  
  Consult with the Package Owner:
  
  If the package is owned by another team or user, consult with them to see if they can grant you access or if they can make the changes for you.
