SAP Error Message - Details

• Message type: E = Error

• Message class: AH - IS-U billing (master data)

• Message number: 759

• Message text: Operand &1 is a register operand

What causes this issue?

The <DS:DE.REG_OPERAND>Operand is a register operand</> indicator is
set for operand &V1&. Therefore, the operand can only be used in a rate
step if this operand is the register operand for the rate. This is not
the case here.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message AH759 - Operand &1 is a register operand ?

  The SAP error message AH759, which states "Operand &1 is a register operand," typically occurs in the context of ABAP programming, particularly when dealing with inline assembly or low-level operations that involve registers. This error indicates that the operand being referenced is a register operand, which is not allowed in the context where it is being used.
  Cause:
  The error is usually caused by one of the following scenarios:
  
  Incorrect Operand Usage: The operand specified in the code is a register operand, but the operation or instruction does not support register operands.
  Inline Assembly Issues: If you are using inline assembly within ABAP, the syntax or the context in which the register operand is being used may not be valid.
  Compiler Limitations: The ABAP compiler may not support certain operations with register operands in the given context.
  
  Solution:
  To resolve the AH759 error, consider the following steps:
  
  Check Operand Type: Ensure that the operand you are using is appropriate for the operation. If it is a register operand, you may need to replace it with a valid memory operand or variable.
  Review Inline Assembly: If you are using inline assembly, review the syntax and ensure that you are using the correct operands as per the assembly language rules.
  Refactor Code: If possible, refactor the code to avoid using register operands in contexts where they are not allowed. Use standard ABAP constructs instead of low-level operations.
  Consult Documentation: Refer to the SAP documentation for the specific ABAP version you are using to understand the limitations and correct usage of operands in your context.
  
  Related Information:
  
  ABAP Documentation: Check the official SAP Help Portal for detailed information on ABAP programming and inline assembly.
  SAP Community: Engage with the SAP Community forums to see if others have encountered similar issues and how they resolved them.
  Debugging Tools: Use debugging tools available in the ABAP Workbench to trace the execution and identify where the error occurs.
