Customizing settings missing for company code XXXX, form ID X Message No. FAPM020

Hi All,

I am trying to create a correspondence for Check Returns. I have created the Return Lot via FP09 and was posted without any issues, but when i try to generate the return letter correspondence via FPCOPARA , I am being presented with message "Customizing settings missing for company code XXXX, form ID X Message No. FAPM020". I am missing something here? I have configured all the return reasons and forms. Please advise.

Thanks,
