Hi @MuzYashoN 

I can think of below differences

• Availability exceptions may be generated for all the inventory parts of a site, or a selection of inventory parts for a site regardless of how they are controlled. It is possible to create exceptions for, e.g., MRP controlled parts, order proposal controlled parts, or parts that are manually controlled. But actional proposal can be generated for the MRP controlled parts
• Availability exceptions supports only limited message type but action proposal support wider range of message types
• Action proposal provide more detailed information where it is possible to redirect to the source using action proposal messages (eg. purchase order, customer order, shop order etc) and to perform the MRP proposed changes such as reschedule orders or change quantity. But this can be possible through exception message
• Action proposal support multi-level analysis where it is possible to navigate to the previous level or next level action proposals 

Hope this helps!!

Hi,

Very good answer from Vithun as always.

Just wanted to highlight the beauty of Availability Exceptions:

1. It works for ALL parts
2. It uses same data source as the Inventory Part Availability Planning / All tab
   ...which makes it easy to explain :-)

However, as Vithun points out, MRP action proposals are much more comprehensive

And you do get the valuable hints from it like for example the messages:

• Remove Order - pointing to the order
• Late Order - pointing to the order -  and number of days late
• Early Order - pointing to the order - and number of days early

Personally, when working with MRP planned parts, I tend to look into MRP Action proposals rather than Availability Exceptions.

Cheers,

Mats
