Once, create a DW composed of multi-table (data window object)
When making it update. Discover DW_1.Update () always = -1. This is the data that the data cannot be updated!
Check the Update property settings of the data window object, found that there is no settings in it!
After the setting, the DW update can be successful.
The last few tests, summary:
------------------------------
If your DW structure is from a table full field, the update property is automatically plus, do not set this step;
But if you are from multiple monologues, there will be no update properties, and you will be adjusted by manual;
If it is originally not all fields, then modify add a field, this field is not in the Update property, to handle it.
If it is a multi-table, once the modified data field (such as adding a field), the original UPDATE attribute has fully failed.
------------------------------------------------
Remember these experiences, so as not to go wrong later!
