• What is the cause and solution for SAP error message 01655 - Specify a linkage (AND/OR) ?

  The SAP error message "01655 Specify a linkage (AND/OR)" typically occurs in the context of query definitions or selection criteria in SAP systems, particularly when using the SAP Query tool or similar functionalities. This error indicates that the system expects you to specify a logical operator (AND/OR) to connect different conditions or criteria in your query or selection screen.
  Cause:
  The error arises when:
  
  You have defined multiple selection criteria or conditions in your query, but you have not specified how these conditions should be linked (i.e., whether they should all be true at the same time using AND, or if at least one of them should be true using OR).
  The linkage is missing in the query definition, leading the system to be unable to process the request correctly.
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Open the Query Definition: Go to the transaction where you are defining your query (e.g., SQ01 for SAP Query).
  
  
  Check Selection Criteria: Review the selection criteria you have set up. Look for any conditions that are defined without a logical operator.
  
  
  Specify Linkage:
  
  If you have multiple conditions, ensure that you specify how they should be linked. You can do this by selecting the appropriate logical operator (AND/OR) from the options available in the query definition screen.
  For example, if you have two conditions, you can choose to link them with AND if both conditions must be true, or with OR if at least one of the conditions should be true.
  
  
  
  Save Changes: After specifying the linkage, save your changes and try executing the query again.
  
  
  Test the Query: Run the query to ensure that it now executes without errors.
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for more details on query definitions and selection criteria.
  SAP Community: You can also check forums and community discussions for similar issues and solutions shared by other SAP users.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SQ01 (SAP Query), SQ02 (InfoSet), and SQ03 (User Groups) for better navigation and understanding of the query environment.
  
  If the problem persists after following these steps, consider checking for any additional settings or configurations that might be affecting the query execution, or consult with your SAP administrator for further assistance.
