• What is the cause and solution for SAP error message AQ_AD_HOC054 - Query contains more than one list. The first list will be opened ?

  The SAP error message AQ_AD_HOC054 indicates that a query you are trying to execute contains more than one list, which is not allowed in the context of the query you are running. This typically occurs in the context of SAP Query or SAP Ad Hoc Query when the query is designed to pull data from multiple sources or when there are multiple selection criteria that result in more than one list being generated.
  Cause:
  
  Multiple Lists in Query: The query is attempting to generate more than one list of results, which is not supported in the current context.
  Incorrect Query Design: The query may have been designed in a way that inadvertently creates multiple lists, such as using multiple selection criteria or joins that lead to multiple outputs.
  Data Model Limitations: The underlying data model may not support the way the query is structured, leading to conflicts in how the data is retrieved.
  
  Solution:
  
  Review Query Design: Go back to the query design and check the selection criteria. Ensure that you are not inadvertently creating multiple lists. Simplify the query if necessary.
  Consolidate Lists: If your query is pulling from multiple tables or sources, consider consolidating the data into a single list or using a different approach to retrieve the data.
  Use Subqueries or Joins: If you need to pull data from multiple sources, consider using subqueries or joins that can combine the data into a single output.
  Check for Filters: Ensure that any filters or selection criteria are not causing the query to generate multiple lists. Adjust them as needed.
  Test with Simplified Query: Create a simplified version of the query to see if it executes without errors. Gradually add complexity back to identify the specific cause of the issue.
