A dynamically specified FROM clause has an unexpected format.
Please see abap error for more details about the possible cause of this runtime error and how it could be avoided.
The running ABAP program attempted to execute an Open SQL statement in
which a FROM clause was specified dynamically in the field <runtime parameter>. This
FROM clause contains an OUTER JOIN. For this case, in Open SQL there is
the restriction that all comparisons of two table columns in ON
conditions must be comparisons between columns of the left join-operand
and columns of the right join-operand. In this particular case, this
restriction is violated.
