SAP Error Message - Details

• Message type: E = Error

• Message class: 5P - Error Messages for Schema, Pers.Calc.Rule and Feature Checks

• Message number: 261

• Message text: &: Assignment for key & in & is invalid

What causes this issue?

You have assigned the variable key of a subfeature to a main feature.
This assignment follows a decision operation in which the field name
is not marked in the main feature structure and is thus not permissible
in this branch of the tree.

How to fix this error?

Since the field name is not permissible for the main feature, the
tree branch for the subfeature is cut off when a decision operation
with this field name occurs. All assignments beneath this are thus
invalid. You must either delete the assignment or mark the field
name in the main feature structure.
