Difference between Ijma' on transmission and Ijma' on opinion

What is the difference between *Ijma' on the transmission* (الإجماع على النقل) and *Ijma' on the opinion*? (إجماع في الرأي). Apparently, they are sub-categories of Ijma (الإجماع) but what is the precise difference between the two? **Update:** This is where I found the following text > أما **الإجماع في الرأي** فليس بحجة عند أكثر الأصوليين، وعند طائفة كبيرة من > المالكية > ... > أما **الإجماع على النقل**، فهو ليس بحجة عند غير المالكية، واتفق المالكيون > على حجيته > ... Translation: > "As far as **the ijma' on opinion** is concerned, it is not a *hujjah* > according to the majority of the scholars of *Usul* and a considerable > group among Malikites...whereas **the ijma' on transmission** is not a > *hujjah* according to non-malikites and there is a consensus among malikites on it being the *hujjah* ..."
