Hi

Refering to Specification Doc giving a description for Fix Protocol it is noticed that it is permissible for fields to be repested within a repeating group.
For this aim the NoXXX field (“which specifies the number of repeating group instances”)should be a number.
My problem is that for the following field “116 _ OnBehalfOfSubID” is a string (“Assigned value used to identify specific message originator (i.e. trader) if the message was delivered by a third party” as explained in Fiximate Message)so I can’t assign to it the role number???
My question is whet should I do for this case ? Do I use this field “116 _ OnBehalfOfSubID” with the format “String” for The FixMessage or should it be replaced by an another field name with the format “number”?

Thanks

Hi Imen,

as nobody else answered…

repeating group. For this aim the NoXXX field (“which specifies the
number of repeating group instances”)should be a number.

OK, but only a defined set of fields (as given in the FIX specs) can be part of a repeating group. In other words: for each message type, every field is either part of a repeating group or not, but not both.

My problem is
that for the following field “116 _ OnBehalfOfSubID” is a string
(“Assigned value used to identify specific message originator (i.e.
trader) if the message was delivered by a third party” as explained in
Fiximate Message)so I can’t assign to it the role number??? My question

OnBehalfOfSubID” with the format “String” for The FixMessage or should
it be replaced by an another field name with the format “number”?

If I understand you correctly, you want to have multiple instances of OnBehalfOfSubID in one FIX message (header)?

In the standard FIX spec, this is not possible: OnBehalfOfSubID is not part of a repeating group.

What kind of business concept do you intend to implement using OnBehalfOfSubID?
