# SecondaryAllocID <793> field

## FIX 5.0 SP2 EP299

### Description

 Type: [String](https://www.onixs.biz/fix-dictionary/5.0.sp2.ep299/index.html#String)

 Secondary allocation identifier. Unlike the [AllocID <70>](https://www.onixs.biz/fix-dictionary/5.0.sp2.ep299/tagNum_70.html), this can be shared across a number of [AllocationInstruction <J>](https://www.onixs.biz/fix-dictionary/5.0.sp2.ep299/msgType_J_74.html) or [AllocationReport <AS>](https://www.onixs.biz/fix-dictionary/5.0.sp2.ep299/msgType_AS_6583.html) messages, thereby making it possible to pass an identifier for an original allocation message on multiple messages (e.g. from one party to a second to a third, across cancel and replace messages etc.).
