I've had this a few times and never found an answer. I [sometimes] find that a query from an API will not return me the name of the related field, only the ID.
Here is an example:
API call using POSTMAN:
Names are filled out here OK...
API call using C# program:
Note how the enh_po_pricematrix_c and enh_so_pricematrix_c is empty string.
Anyone know why? it's a lot more cumbersome to do another lookup on ID or related module.
I've figured out that price_pricematrix_id1_c is id for enh_so_pricematrix_c and price_pricematrix_id_c is enh_po_pricematrix_c.
