W8156 - Details

• SAP Error Message:
  W8156 - Cursor does not show binding direction
  
  
  Cause:
  This warning message typically occurs in the context of ABAP programming when dealing with cursor variables in Open SQL or Native SQL statements. The message indicates that the cursor declaration or usage does not specify the binding direction (input/output) for the cursor parameters.
  In other words, when you declare or use a cursor in ABAP, the system expects you to specify whether the cursor parameters are used for input (passing values into the cursor), output (returning values from the cursor), or both. If this direction is missing or ambiguous, the system raises this warning.
  
  When does it occur?
  
  When using cursor variables in Native SQL or Open SQL.
  When the cursor parameters are not explicitly declared with the binding direction (IN, OUT, or IN OUT).
  Possibly when using host variables in cursor declarations or FETCH statements without specifying direction.
  
  
  
  Solution:
  
  
  Specify the binding direction explicitly in the cursor
