CDS12077Relation Error: A valid value must be supplied in Data Element 2 as Data Element 1 is present
Completing one data element with a particular value requires another value, in the same element or a different one, and that second value is missing or incomplete.
What to check for CDS12077
- Every element that depends on the one you completed.
- Whether a related element has been completed in full; HMRC's examples include an incomplete address where a party name has been given.
- Whether a code entered in one element requires a further code alongside it.
What to check across the Relation, authorisation and sequence errors
Two elements, or a value and a rule, disagree. Read both elements together: completing one element with a particular code often requires another value, and the fault is frequently in the element you did not change. The family also covers parties and authorisations that are not recognised, references that must be unique, and messages sent out of sequence.
What does CDS12077 mean?
CDS12077 is a relation error: because one data element is present, another must carry a valid value, and it does not. HMRC's examples include an incomplete address where a party name has been given. Check every element that depends on the one you completed, including elements elsewhere on the declaration.
