I had created this function, Substring([contact_history_vw/@mktg_promo_cell_key], 13, 6), for the following formula: Substr(MKTG_PROMO_CELL_KEY, 13,6).
The expression is expressed in Adobe Campaign as, "sub string of mktg_promo_cell_key for ita_contact_history_vw starting at offst 13 of length 6":
Not having access to the actual data field, "MKTG_PROMO_CELL_KEY," assuming that the values are CHAR, what does, "starting at offset 13 of length 6" mean?
Is this correct Substring function for the query formula, "Substr(MKTG_PROMO_CELL_KEY, 13,6)"?
Sorry, didn't mean to duplicate thread, I believe I clicked post it twice, not intentionally.
Sorry for the error,
