Hi Justin,
If I understand your description correctly, your question is about nested tables and not page breaks (i.e. the end of a page is reached and how to handle that).
For nested tables the data has to be structured accordingly, i.e. in your case it looks like all 4 items for GT_SERNUM_EMPTY are under the first entry for VBLKP. You'll need to adjust your print program to provide the data complying with your context structure.
You can verify this by looking at the data that is used for rendering the form (e.g. turn trace on and to the highest level).
