SALV_BS_MSG308 - Overview

• Message type: E = Error

• Message class: SALV_BS_MSG -

• Message number: 308

• Message text: Only one operator is allowed for each filter condition

What causes this issue?

Comparison operators ("<(><<)>", ">", "<(><<)>>", ...) and value ranges
(identified with hyphens) are used in filter conditions. Only one
operator or hyphen is permitted for each filter condition. However more
operators and/or hyphens are used in this condition.

System Response

The filter condition is not used.

How to fix this error?

If a filter value contains multiple operators and/or hyphens, enclose
the entire filter value in double quotation marks.
Example:
If a column is to be filtered by the value AB-CD-001, the filter value
must be enclosed in double quotation marks. In this case, the correct
notation is ?AB-CD-001?.

SALV_BS_MSG308 - Details

• The SAP error message SALV_BS_MSG308 indicates that there is an issue with the filter conditions applied in an ALV (ABAP List Viewer) report. Specifically, it means that you have used more than one operator in a single filter condition, which is not allowed.
  
  Cause:
  The error occurs when you try to define a filter condition with multiple operators (like AND, OR) in a single condition. For example, if you have a filter condition that looks like this:
  Field1 = 'Value1' AND Field2 = 'Value2'
  This would trigger the error because it combines two conditions with an AND operator in a single filter.
  
  Solution:
  To resolve this error, you need to separate the filter conditions into distinct entries. Instead of combining multiple conditions in one, you should create separate filter conditions for each operator. For example:
  
  Create one filter condition for Field1 = 'Value1'.
  Create another filter condition for Field2 = 'Value2'.
