ERS - Invoice cancelation

Hi,

We have created a ERS invoice using MRRL transaction. In the delelopment client if I try to reverse the invocie using MR8M, I am getting the error message that "Invoice doc. 5105600571/2010 was created via evaluated receipt settlement" but I am not getting the same error in Quality system, where I can use MR8M and reverse the ERS invoice.

Please let me know what could be the possible reason for that.

I have compared the configuration in development and Quality client and there is no change.

Please help.

Regards,

AG
