  SAP Error Message:
  
  WPS01119
  
  Text: Parent task list key &1 / ext. ID &2: No internal number possible
  
  Cause
  This error occurs when you try to create or assign a parent task list with a specific external ID, but the system cannot generate or assign an internal number for the task list. The internal number is mandatory for task lists in SAP, and if the number range for the task list type or group is exhausted or not properly maintained, the system cannot create a new internal number.
  Common causes include:
  
  Number range for the task list group or type is not defined or has reached its limit.
  Number range object for the task list is not properly configured.
  Incorrect or missing number range assignment in the task list group or task list type.
  Customizing or master data inconsistency related to task list numbering.
  
  
  Solution
  
  
  Check Number Range Configuration:
  
  Go to transaction SNRO or SNUM.
  Enter the number range object for task lists, typically TASK or a similar object depending on your SAP system and configuration.
  Verify if the number range intervals are defined and if there are available numbers left.
  If the number range is exhausted, create a new interval or extend the existing one.
  
  
  
  Check Task List Group and Type Settings:
  
  Use transaction IA05 or IA06 (depending on your SAP version) to check the task list group and type.
  Verify that the number range is assigned correctly to the task list group/type.
  Ensure that the external ID and internal number assignment settings are consistent.
  
  
  
  Adjust Number Range Assignment:
  
  If the number range object is missing or incorrect, assign the correct number range object to the task list group/type in customizing.
  Use transaction SPRO ? Plant Maintenance and Customer Service ? Maintenance Processing ? Task Lists ? Define Number Ranges for Task Lists.
  
  
  
  Check for Customizing or User Exits:
  
  If custom logic or user exits are involved in task list creation, verify that they do not interfere with number assignment.
  
  
  
  Re-try Task List Creation:
  
  After fixing the number range or assignment, try to create or assign the parent task list again.
  
  
  
  
  Related Information
  
  Task List Number Ranges: Task lists in SAP PM/CS use internal numbers for identification. These numbers are controlled by number range objects assigned to task list groups and types.
  Transactions:
  
  SNRO - Number Range Objects
  SNUM - Number Range Maintenance
  IA05 / IA06 - Task List Group/Type Maintenance
  IA01 / IA02 / IA03 - Create/Change/Display Task List
  
  
  SAP Notes: Check SAP Notes related to task list number range issues if the problem persists.
  External ID: The external ID is often a user-defined identifier; the system still requires an internal number for processing.
