Products disappearing from sales orders
We have our web store integrated with Zoho CRM via the API so that when a customer places an order it automatically gets inserted into Zoho as a Sales Order. It's been working fine for many months. The sales order is added to a temporary account and when we process it we create a new account for the customer and move the sales order to that account.
Yesterday we began having a problem where when we move the sales order to the new account all of the products in the sales order except for the first one disappear from the sales order. The list price totals don't change, so they're not being recalculated but the only line item that remains in the sales order after the move is the first one. The products are definitely there when the sales order is first inserted. They don't seem to disappear until we try to move the sales order from the temporary account to the new customer account.
It's a very weird problem. Any ideas? Did anything change over the past few days that could be causing or triggering this problem? I suppose it's possible we're doing something wrong when we insert the sales order via the CRM API but I don't know what we could be doing wrong and our integration worked fine from last September until yesterday.
