No other MS Word applications must be opened during the transfer. If an application is opened before the transfer, it shouldn't be activated.
Maximum 5000 letters can be used in a key string.
The key string variables are order-dependent. If the next field will be used without using the preferred field, "#" sign must be used for the unused field. The string can be terminated without # sign if a new variable will not follow the last one.
"#", "&" and "$" special characters are reserved for the key string, and should not be used for data.
The data in hierarchical dependency (such as header-line relation) must be transferred in separate layers. Therefore, the fields to be used in filtering can only be selected from the transferred layer.
