MiFID Fields Mapping: Buyer decision maker code/Seller decision maker code

1

Hi Team,

There are two MiFID fields which we would like to discuss to know what FIXML fields to be used for mapping

Field no: 12 - Buyer decision maker code
Description - Code used to identify the person who makes the decision to acquire the financial instrument.Where the decision is made by an investment firm, this field shall be populated with the identity of the investment firm rather than the individual making the investment decision. Where the decision maker is a legal entity, the LEI code of the decision maker shall be used.Where the decision maker is a non-legal entity, the identifier specified in Article 6 shall be used.

Field no:21 - Seller decision maker code
Description - Code used to identify the person who makes the decision to sell the financial instrument.Where the decision is made by an investment firm, this field shall be populated with the identity of the investment firm rather than the individual making the investment decision.Where the decision maker is a legal entity, the LEI code of the decision maker shall be used.Where the decision maker is a non-legal entity, the identifier specified in Article 6 shall be used.

Our initial thoughts are to use tag 452 PartyRole @R = 122 [Investment decision maker]. Could you please advise what (tag 447) PartyIDSource @Src should be used in these cases?

Regards,
Rahul

Hi Rahul -
For LEIs, you should set PartyIDSource to N. For natural persons, Q (National ID of natural person) is the most appropriate value - it was added for this purpose in EP222

@andrewlynch Thanks for your response. Much appreciated.

@andrewlynch Can you also please comment whether using Party Role (tag 452) = 122 is the correct mapping for the MiFID fields 12 (buyer decision maker code) and 21 (seller decision maker).

We already uses Party Role = 122 for Investment Decision Maker Within Firm (field 57).

Is there a MiFID mapping to FIX available to refer to?

Regards
Rahul

@rahulmohanraj, Take a look at the EP232. The pdf in that zip file you can download once you login to the FIX website has the entire RTS 22 mapped to FIX in Table 1. If you still have questions after looking through that, the please post back here.
