How To Fix FL701 - Function group & is SAP-specific

SAP Error Message - Details

• Message type: E = Error

• Message class: FL - Function Builder messages

• Message number: 701

• Message text: Function group & is SAP-specific

What causes this issue?

You attempted to create a customer-specific function module in an SAP
function group. This is not allowed because there is no way to prevent
your modification being lost during the next SAP update and it may lead
to system inconsistencies. The reason lies with the internal numbering
system for generating new function modules. New function modules can
only be added in the relevant development system for the function
group, since duplicated module numbers inevitably result in
inconsistencies and overwrites after an SAP update.
Note that SAP maintains a strict divison between customer-specific
developments and SAP standard software, even in the context of function
groups. This means that any customer-specific function module must be
assigned to a customer-specific function group that has already been
created.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

For your own function modules, use a function group beginning with
<LB>Y</> or <LB>Z</>, i.e. with the format <LB>Zaaa</>. These function
groups are reserved for customers. If you use FORM routines from an SAP
function group frequently, you can call them as includes.
