Using Long Record Names in Chains

in TREP Infrastructure

We have some old apps using Marketfeed chains (longlink fids etc) these have a length of 21 characters but nowadays you can have record names on TREP up to 255 characters. What is the recommended approach if it is desired to use long record names in chains?

    Hello @mwalters

    If you are limited to using chains because of your existing Marketfeed apps then the choices are limited to those provided by the data dictionary:

    The BR_LINK fields allow 32 characters but if your objective is to make use of longer names, e.g. up to 255 characters, then first of all make sure the existing applications/APIs involved are capable of handling it.

    Please note that because there is no existing chain format for names longer than 32 characters this would require a custom chain record using custom FIDs in the dictionary and would not be handled as a chain by existing applications without further development effort.
