Filtering out of planned order &1 changed by BAdI from &2 to &3

What causes this issue?

In SAP APO, you can define for planned order integration if SAP APO
should allow the transfer from SAP R/3 for all planned orders or only
for planned orders in the <DS:GLOS.363D6D1E6AE92097E10000009B38F984>SNP
production horizon</>. You can define this in the Implementation Guide
for Supply Network Planning (SNP) under <LS>Basic Settings </>->
<LS>Maintain Global SNP Settings</>. Settings that you make here affect
the initial data transfer and the change transfer for planned orders.
For more information, see <DS:DE./SAPAPO/SNPINTPRD>Planned Order
Integration</>.
The <DS:SIMG./SAPAPO/DM_SNP_FILT>BAdI /SAPAPO/DM_SNP_FILT</> can be
used to change the system behavior that is defined by the settings
described above. This BAdI is called up in SAP APO inbound.
By means of the BAdI, the indicator for filtering out was changed from
&V2& to &V3& for planned order &V1&. Planned order &V1& is therefore
filtered out or not filtered out, according to the criteria defined in
the BAdI.
If the indicator has the value X, planned order &V1& is filtered out in
the SAP APO inbound and is thus not updated
If the indicator has the value 'initial', planned order &V1& is not
filtered out in the SAP APO inbound and is thus updated in SAP APO
