SAP Screen Personas

In ME51N Transaction I have two fields one for Supplier and the other for supplier Name. When I give the supplier Number and click on Check button, I will get the Supplier Name based on the Supplier Number. I have seen the value is coming from RFC. It is working fine in Development. But I could not get the Supplier Name when I click the Check Button in Quality. I have verified scripting. Everything is same.

Can you help me what might be the issue?

Thank you!!
