SAP Error Message - Details

• Message type: E = Error

• Message class: UPF - Planning Functions

• Message number: 096

• Message text: Variable &1 is not restricted to a single value

What causes this issue?

You tried to execute a formula function with a parameter group, in
which the variable &V1& is referred to. However, this variable is not
restricted to a single value, rather it contains several values or
value areas.

System Response

The function cannot be executed. The data records contained in the
planning package remain unchanged.

How to fix this error?

Check the definition of variable &V1& in the context of the current
planning area and make sure, that the variable is restricted to exactly
one single value. If you do not want to change the definition of the
variable, then create a new variable, which is restricted to a single
value, and alter the parameter group of the formula correspondingly.

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