- Parameter field & is foreign key field in join condition to be built ?The SAP error message E2454 indicates that there is an issue with a parameter field being used in a join condition within a query or report. Specifically, it suggests that the parameter field is a foreign key field, and the system is unable to build the join condition properly due to this.
Cause: Foreign Key Relationship: The parameter field you are trying to use in the join condition is defined as a foreign key in the database. This means it is expected to reference a primary key in another table. Join Condition Issues: The join condition may not be correctly defined, or the foreign key field may not be compatible with the primary key it is supposed to reference. Data Model Issues: There may be issues with the data model or the way the tables are related, leading to ambiguity or conflicts in the join conditions.
Solution: Check Foreign Key Definition: Verify the foreign key definition
