• What is the cause and solution for SAP error message PAIS028 - The query contains more than one list. The first list will be opened ?

  The SAP error message PAIS028 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 working with. This typically occurs in SAP systems when using the SAP Query tool or similar reporting tools that are designed to generate reports based on specific data sets.
  Cause:
  The error is caused by the query attempting to display multiple lists or data sets simultaneously. In SAP, certain queries are designed to handle only a single list of data at a time. When the query is structured to include multiple lists, the system cannot process it correctly, leading to this error message.
  Solution:
  To resolve the PAIS028 error, you can take the following steps:
  
  
  Review the Query Structure: Check the query definition to ensure that it is not set up to generate multiple lists. You may need to simplify the query to focus on a single data set.
  
  
  Modify the Query: If your query is intended to display multiple lists, consider breaking it down into separate queries, each handling a single list. This way, you can run them independently without encountering the error.
  
  
  Check for Joins: If your query involves joins between different tables, ensure that the joins are correctly defined and that they do not inadvertently create multiple lists.
  
  
  Use Subqueries: If applicable, consider using subqueries to isolate the data you need into a single list format.
  
  
  Consult Documentation: Refer to SAP documentation or help resources for guidance on structuring queries correctly to avoid this error.
  
  
  Seek Help from SAP Support: If you are unable to resolve the issue on your own, consider reaching out to your SAP support team or consulting SAP's support resources for further assistance.
