integrity constraint XZXKSYS_C0015985 violated - parent key not found

This error message indicates that there is a violation of an integrity constraint in a database. Specifically, it states that the parent key is not found.

In a relational database, an integrity constraint is a rule that ensures the validity and consistency of data. A parent key refers to a primary key in a parent table, and a child key refers to a foreign key in a child table. The parent key must exist in the parent table for the child key to reference it.

When the error message states that the parent key is not found, it means that the foreign key value in the child table does not match any primary key value in the parent table. This violation prevents the establishment of a valid relationship between the two tables.

To resolve this issue, you need to ensure that the foreign key value in the child table corresponds to an existing primary key value in the parent table. You may need to check your data and make sure that the referenced parent key exists before executing the operation that caused the error.

Additionally, you might need to check if there are any inconsistencies in your database, such as missing or deleted records
