• Message text: Table & exceeds maximum possible length

What causes this issue?

Structure &V1& with a length of &V2& bytes as defined in the Data
Dictionary is transferred to the function module for the sorting of the
open items. However, the internal buffer of the function module can
only process structures with a maximum length of &V3& bytes.

System Response

Further processing of the program has been cancelled.

How to fix this error?

This is an error in the definition of the data structure which is used
to sort the open items. This data structure should contain key fields
and all excess fields which should make sorting possible. Other fields
could possibly also be added. All fields must be provided to the
program which calls up the sorting module. To ensure maximum
performance, you should be careful that the total number of fields is
not too large. The internal buffer of the sorting module is limited to
&V3& bytes. Change the definition of the transferred data structure so
that the total number of fields does not take up more space than this.
