How To Fix OT813 - Line &1: Logical AND block must not be empty

SAP Error Message - Details

• Message type: E = Error

• Message class: OT - SAP Online Correction Support (SOCS)

• Message number: 813

• Message text: Line &1: Logical AND block must not be empty

<ZK>&CAUSE&</>
You have defined import conditions where the "Logical AND Block" field
was specified empty.
The following rules apply to the "Logical AND Block":
The AND block must be filled for all import conditions
The AND block must (for each package) be numbered sequentially (starting
with 1)
Import conditions that are to be valid together have the same AND block
For alternative import conditions, the AND block must be increased by 1
for every alternative 1
<ZK>Note: These rules also apply to equivalent import conditions. Since
another (pseudo) package is referenced here, the numbering starts at 1
again.</>

System Response

The import condition check is terminated.

• What is the cause and solution for SAP error message OT813 - Line &1: Logical AND block must not be empty ?

  The SAP error message OT813, which states "Line &1: Logical AND block must not be empty," typically occurs in the context of ABAP programming, particularly when dealing with logical expressions in conditional statements. This error indicates that there is a logical AND operation in your code that does not have any conditions to evaluate, which is not allowed.
  Cause:
  The error is caused by a logical expression that is incorrectly formed. Specifically, it occurs when you have a logical AND (AND) operator without any valid conditions on either side of it. For example, if you have a statement like:
  IF condition1 AND AND condition2.
  In this case, the second AND does not have a condition following it, leading to the error.
  Solution:
  To resolve this error, you need to ensure that all logical expressions are correctly formed. Here are steps to fix the issue:
  
  
  Check the Logical Expression: Review the line of code indicated by the error message (replace &1 with the actual line number). Look for any logical AND operators that do not have valid conditions on both sides.
  
  
  Correct the Syntax: Make sure that every logical AND has valid conditions. For example, if you have:
  IF condition1 AND condition2.
  Ensure that both condition1 and condition2 are valid expressions.
  
  
  Remove Empty Blocks: If you find any logical blocks that are empty or incorrectly structured, either remove them or replace them with valid conditions.
  
  
  Test the Code: After making the necessary corrections, recompile and test your code to ensure that the error is resolved.
  
  
  Related Information:
  
  ABAP Syntax: Familiarize yourself with the syntax rules for conditional statements in ABAP. Logical expressions must always have valid conditions.
  Debugging: Use the ABAP debugger to step through your code and identify where the logical expressions are being evaluated.
  Documentation: Refer to the official SAP documentation for more details on logical expressions and error handling in ABAP.
  
  By following these steps, you should be able to resolve the OT813 error and ensure that your logical expressions are correctly formed.
