I would like documentation on the RMTES fromat for contribution partial page updates

I am using an internal openmama based MD api which has a UPA based bridge to TREP to send contributions to Refinitiv. I can use it to send page whole line updates, but I cannot get partial line updates to work. I can see a hex representation of a partial page update when I subscribe showing the control characters and column position in the line to put the update. Using the same format to contribute does not work. Note I am interested in the underlying format of the row field value I need to send, not documentation on the way to do it in RFA etc. as I am not using any Refinitiv APIs.

@Michael Moore

The partial page update format has been explained in the legacy Marketfeed document. There are two formats.

1. Intra-Field Position Sequence

It is used to update the data at a specific position

<CSI>n<HPA> 

2. Character Repetition

It is used to save bandwidth by replacing strings of the same repeated character with a special short sequence:

<char><CSI>n<REP>

For more information, please refer to this How to retrieve page-based data using Tick History REST API article.

Hello @Michael Moore

Please refer to section 2. Partial field update in How to parse page-based data using Elektron SDK Java article. The section explains the format of partial field update.
