How To Fix FDT_CORE2031 - Default setting for NUMC comparison changed, manual steps are necessary

FDT_CORE2031 - Overview

• Message type: E = Error

• Message class: FDT_CORE2 - BRFplus core functions (in addition to msg class FDT_CORE)

• Message number: 031

• Message text: Default setting for NUMC comparison changed, manual steps are necessary

What causes this issue?

You have changed the application default setting for the comparison
style for element data objects bound to data elements of type NUMC. The
new setting is in effect for new data elements bound to NUMC fields as
well as for existing data elements that are newly bound to a NUMC field.
As opposed to that, the comparison style used for already existing data
elements bound to a NUMC field remains unchanged. This is because both
possible comparison styles (numeric as well as alphanumeric) are valid
options, and it is up to you to decide in each single case which
comparison style is required depending on the use case.

System Response

All newly created data objects bound to a NUMC field will consider the
new setting.

How to fix this error?

Depending on the new setting there are some steps to be done to migrate
your currently existing data objects to use the new default. This
affects only data objects with a DDIC binding to a NUMC field.
Numeric comparison was turned on
All data objects bound to a NUMC field have to be rebound to use numeric
comparison.
All functions referencing such objects must be regenerated. The system
automatically takes care of this when the data objects are rebound.
Numeric comparison was turned off
All data objects with a binding to a NUMC field have to be rebound to
use alphanumeric comparison
All functions referencing such objects must be regenerated. The system
automatically takes care of this when the data objects are rebound.
