We are using the Data Management Framework (DMF) to release products via Excel template uploads. Our requirement is to ensure that the case of the item number in the Released Products entity exactly matches the case of the item number in the Products entity.

For example:

• If a product is defined in the Products entity as ABC123, then it should only be released as ABC123.
• If the Excel upload contains abc123, the system should reject the release, even though the characters match in a case-insensitive comparison.

This is to enforce strict case-sensitive consistency between the product definition and the released product, and to avoid discrepancies caused by case mismatches. We are not requesting changes to the data model or entity relationships. We are simply looking for a way to validate the case of the item number during the release process via DMF.
