Erroneous sorting of rows of an internal table.
Please see abap error for more details about the possible cause of this runtime error and how it could be avoided.
In the ABAP Debugger, the control-switch for the sorting of internal
tables before statements of the form "READ ... BINARY SEARCH", was
activated.
In this particular case, the lines <runtime parameter> and <runtime parameter> of the table <runtime parameter>-NAME
were not sorted according to the key specified in the READ statement. As
the statement "READ ... BINARY SEARCH" expects the table to be
correctly sorted, generally an incorrect entry is located.
