So I have a document library with date, alert and alert-date fields.
The date and alert fields are completed when a doc is uploaded, and there is a workflow which takes the alert away from the date (and also takes an extra day off) and sets it as the alert-date. E.g. If the date is 15/07/2013, and the alert is 1 month, the workflow sets the alert-date to 14/06/013 (15/07/2013 - 1 month and a day). The alerts have options of 1 month, 3 months, 6 months or 1 year. A extra day is always taken off as these workflows are triggered by information management policy which only allows conditions of +1 day (the day is taken away via the workflow and then added via information management policy).
The problem comes when a .docx file is uploaded, as all the alert-dates (even if they relating date and alert aren't populated) are set to 01/01/1900.
I know SharePoint workflows pretty well and have never come across this problem before, so was just wandering if anyone else has and knows a solutions?
Thanks,
Josh.
