From gltr_hist need to find what sales order it came from

[nate100]

From a given gltr_hist record, how can I figure out what sales order it came from?
I see gltr_doc may be of use but not sure how to tie it tall together.

Thank you.

If the posted entry has come from the SO module (gltr_tr_type = "SO"), the Document field (gltr_doc) should contain the invoice. You can obtain the sales order from a few different places, but the easiest way is probably via the Invoice History table (ih_hist where ih_inv_nbr = gltr_doc).
