Interactive Planning area - No plannable

Question

We just upgraded to SCM 5.0. We are getting errors when running the interactive planning area.
When we select a single products and try to load into our planning book, we are getting no plannable characteristic combination.  When we select multiple products, the products load. 
Any ideas on why it works for multiple and not one?

Answer 1

Here is what we completed to fix our problem.
Run report /SAPAPO/OM_LC_UPGRADE_50 via TCODE SE38. In section
C - At End of Upgrade, and perform steps 4 - 7.
If you run transaction /NRSRV; >All Elementary Tests; >>Database;
Double-click >>>Check Database Parameter(s)<<<
++EXECUTE++
You will find 2 red lights there.
ORACLE: Parameter OPTIMIZER_FEATURES_ENABLE is set to value 9.2.0
(recommended value is 10.x)
Message no. RSCV527
This is related to our problem, which is due to a big issue in Oracle
10.*. You might need to get your Oracle admin involved to change the
parameters.
ORACLE: Parameter OPTIMIZER_MODE is set to value CHOOSE(recommended
value is ALL_ROWS).
In most cases the /SAPAPO/DELETE_LC_ANCHORS report did not run for the
affected client during the last LiveCache initialization due to one of
the following configuration errors:
/SAPAPO/DELETE_LC_ANCHORS was not entered as post-processing step
for LiveCache initialization. In LC10 press the pencil button (and the
administration reports tab if necessary) to check this setting.
The RFC destination was not set up (correctly) for the affected
client during LiveCache initialization. See note 305634 for more details
