How To Fix FL709 - Dialog module name is reserved for SAP

FL709 - Overview

• Message type: E = Error

• Message class: FL - Function Builder messages

• Message number: 709

• Message text: Dialog module name is reserved for SAP

What causes this issue?

You attempted to create a dialog module with a name which lies in the
SAP naming range. This is not permitted because any future SAP upgrade
could cause your modification to be lost. Moreover, it could result in
inconsistencies in the system due to the internal numbering system used
when creating new function modules. You can only create new dialog
modules in the development system of the relevant function group.
Duplicate module numbers inevitably lead to inconsistencies and to
objects being overwritten during the next SAP upgrade. In addition, SAP
has a policy of strict separation between function groups containing
customer-specific functions and those containing SAP standard software.
Therefore, any function group which is to contain a customer-specific
dialog module must be created as a customer-specific function group.

System Response

How to fix this error?

The names you use for your own dialog modules should begin with
<LB>Y_</> or <LB>Z_</>. SAP has reserved this naming range specially
for customers' own use.
