  SAP Error Message:
  
  WPS01012 - Enter group counter for the task list
  
  Cause:
  This error occurs when you are trying to create or change a task list in SAP, and the system requires you to specify the Group Counter for the task list but it has not been entered.

  The Group Counter is mandatory because it uniquely identifies a task list within a group. If it is missing, the system cannot process the task list correctly.
  
  Solution:
  
  When creating or changing a task list, enter the Group Counter in the relevant field.
  If you do not know the correct Group Counter, you can:
  
  Use the search help (F4) on the Group Counter field to find existing counters.
  Create a new Group Counter if necessary (depending on your authorization and configuration).
  
  
  Ensure that the Group and Group Counter combination is unique for the task list you are working on.
  If you are using a custom transaction or interface, verify that the Group Counter is being passed correctly.
