Cross-validation rules (CVRs) are used within the Oracle financial systems to prevent the creation of invalid 33-digit account strings (CCIDs). Each cross-validation rule dictates what ranges of values may be used in combination with one another. Thus, for example, a very simple rule might specify that only Org values 23200 through 24499 may be used with Tub 275 (SPH). Use the [chart of accounts validator tool](https://finapps-prod.huit.harvard.edu:8000/OA_HTML/OA.jsp?page=/oracle/apps/huicx/huglCoaVal/webui/huglCoaValPG) to check for errors.

CVRs are applied system wide to all system users. Whenever any component of the Oracle Applications attempts to create a new 33-digit account (a combination of segment values that has not previously been used), Oracle checks all the cross-validation rules to ensure that the combination is valid. If the combination fails to pass a rule, the error message associated with that rule is presented. Whatever transaction was in process is not allowed to continue until it has a valid 33-digit combination.
