I am in the process to set up "GR message" function. I have created a condition record for MLGR "X- MP -7-4 -EN", leaving the Partner field blank and didn't assign the Dummy Recipient. After GR the MLGR message can be created automatically. But the recipient is not the purchasing group, instead is my own user name.
I checked the MLGR configuration, it looks fine. What settings did I miss and where should I look for in order to have the mail sent to the purchasing group?
You should create a new condition type for MLGR base on purchasing group and maintain the relevant condition record again, that will be fine! Because the default condition type can not do that you want!
