Material Description Validation

Hello,

We have written a validation on Material Description and the error is being thrown as expected.

But the Requestor is still able to Submit the request despite the error.

We tried to configure this validation in the BADI USMD_RULE_SERVICE but we're not getting data of field MAKTX in the BADI Class.

Can anyone please guide us as to how we can prevent the requestor from being able to submit when the description error is thrown?

Thanks,

Sagar Dixit
