Diagnosis
More than one masking symbol has been defined for info structure &V1&.
However only one symbol is permitted (apart from a blank character).
Symbol &V3& is filled in the other entries.

Procedure
Instead of '&V2&', enter the symbol '&V3' or the blank character.
If the blank symbol is entered, then no collective product allocationsare used for this product allocation step (even if they are entered inthe planning hierarchy).
