Syntax on Sdata Contract query to restrict data set returned.

SUGGESTED

Can anyone help me, I am working with developers to help them pull data from sage 100 2019 using Sdata.

Using say the customer contract bellow,  they want to make the XML return to be much smaller and only need about a dozen fields from the customer table.

What is the syntax to only have it pull specfic fields on the customer dump.   Can you also do a range of customer numbers as well?  Example query bellow which returns all data elements.

Thank you,
