Sage v2017 ADV - Client needed to change ship to codes from two character to four character to comply with customer's internal codes. So I changed open SO's, AR Invoice History Header and SO history ship to codes. Now there is an issue with ship to history accessed via item maintenance history tab and drilling down to the customer ship level from there. See attached. While I have waded into it deeply, I suspect that this table is summarized by item, customer, ship to, year and month. If so, I am envisioning a complete rebuild of the tables. Can someone confirm this? What table(s) are in play here? TIA.
