Unable to create RFQ in ME41 transaction

Hi,

I have been trying to create RFQ in ME41 transaction after providing the requisite entries. After click on Save button, I get a message mentioning "Document Created <RFQNum> and immediately I get a popup "Express document Update was terminated recieved from author <username>. And the RFQ number is not available in Table EKKO.

Kindly suggest what should be the issue causing the RFQ created to be terminated.

Thanks in advance.

Thanks,

Guru
