• What is the cause and solution for SAP error message SWF_RLS_001160 - The left operand of operator '&1' must not be a table ?

  The SAP error message SWF_RLS_001160 indicates that there is an issue with the use of an operator in a workflow or a related ABAP program where the left operand is expected to be a single value but is instead a table. This typically occurs in the context of workflow conditions or expressions where the syntax or logic is not correctly defined.
  Cause:
  The error arises when:
  
  You are trying to use a table (internal table) as the left operand of an operator (like =, <>, >, etc.) that expects a single value.
  The condition or expression is incorrectly formulated, leading to a mismatch in expected data types.
  
  Solution:
  To resolve this error, you should:
  
  Check the Expression: Review the workflow condition or the ABAP code where the error occurs. Ensure that the left operand is a single value and not a table.
  Use Appropriate Indexing: If you need to compare a value from a table, make sure to reference a specific index of the table. For example, if you have an internal table itab, use itab-index to refer to a specific entry.
  Modify the Logic: If the logic requires checking multiple entries, consider using a loop or a different approach to handle the table data correctly.
  Debugging: If you are unsure where the error is occurring, use debugging tools to step through the workflow or ABAP code to identify the exact line causing the issue.
  
  Related Information:
  
  Workflow Conditions: Familiarize yourself with how conditions are defined in SAP workflows. Ensure that you understand the data types being used.
  ABAP Programming: If you are working with ABAP, review the syntax for operators and how to handle internal tables. The ABAP documentation can provide insights into proper usage.
