How To Fix VQ298 - Not every characteristic has a formula

SAP Error Message - Details

• Message type: E = Error

• Message class: VQ - SD Archiving and Product Allocation

• Message number: 298

• Message text: Not every characteristic has a formula

What causes this issue?

Some features in the info structure &v1& are filled via a source field
rather than via a formula.

System Response

The formulae for the features take into account the entries from the
planning hierarchy. If a feature from the order is not contained in the
planning hierarcy, then the feature is filled with a masking symbol.
No update to the collective product allocations is carried out for
features for which no formulae are entered.

How to fix this error?

If you want to use collective product allocations, enter a formula for
every feature.
The formulae must be adopted for the info structure and its structure.
Formulae 141 to 144 can be used as references.
If you do not want to use collective product allocations (masking
indicator is empty) then you can do also do without the formulae for
the features.

• What is the cause and solution for SAP error message VQ298 - Not every characteristic has a formula ?

  SAP Error Message:
  
  VQ298 - Not every characteristic has a formula
  
  Cause:
  This error occurs in SAP Variant Configuration (LO-VC) when you try to create or process a variant configuration model, and some characteristics in the class or configuration profile do not have an associated formula defined, but the system expects one.
  In particular, this happens when:
  
  You have characteristics that are supposed to be calculated or derived via formulas (e.g., dependencies, constraints, or derived values), but no formula has been assigned to them.
  The system expects a formula for every characteristic involved in a calculation or dependency, but one or more characteristics are missing these formulas.
  This can also occur during the generation of a configuration profile or when activating dependencies if the system detects incomplete formula assignments.
  
  
  Solution:
  
  
  Check Characteristics and Formulas:
  
  Go to the class or configuration profile where the error occurs.
  Identify all characteristics that are part of the configuration.
  Verify if each characteristic that requires a formula (e.g., those used in dependencies or constraints) has a formula assigned.
  
  
  
  Assign Missing Formulas:
  
  Use transaction CU01 (Create Class) or CU02 (Change Class) to check characteristics.
  Use transaction CU50 (Change Dependency) or CU53 (Change Procedure) to check formulas.
  For each characteristic missing a formula, create or assign the appropriate formula.
  Formulas can be created using the formula editor in SAP, typically in the dependency or procedure maintenance screen.
  
  
  
  Check Dependencies and Procedures:
  
  Review all dependencies (preconditions, selection conditions, procedures) to ensure that all characteristics involved have formulas if required.
  Make sure that the formulas are syntactically correct and active.
  
  
  
  Activate and Test:
  
  After assigning formulas, activate the class and dependencies.
  Test the configuration to ensure the error no longer appears.

  Transactions:
  
  CU01 / CU02 – Create/Change Class
  CU50 / CU53 – Create/Change Dependencies and Procedures
  CU56 – Create/Change Formulas
  CU60 – Configuration Profile Maintenance
  
  
  
  SAP Notes and Documentation:
  
  Check SAP Notes related to variant configuration formulas and dependencies.
  Review SAP Help Portal documentation on Variant Configuration, especially sections on formulas and dependencies.
  
  
  
  Common Scenario:
  
  When creating complex configuration models, formulas are often used to calculate characteristic values or enforce constraints.
  Missing formulas can cause the system to throw this error during activation or configuration.
  
  
  
  
  Summary:
  Error VQ298 indicates that some characteristics expected to have formulas do not have them assigned. To resolve, identify these characteristics and assign the necessary formulas in the variant configuration model, then activate and test the configuration.
