An answer will be different for each product, and product-specific which can't be applied to another product.
Can you provide the product that you are using, please?
Hello @ronnel.m.vinuya,
Looks like your question is not API-specific. Rather, you are trying to clarify the RICs,
required to request the contract content from Elektron data feed.
Is this correct?
If this is the case, the best way to get the answer quickly is to open a service request at My Account Raise A Case or call Thomson Reuters Helpdesk to inquire.
