Treating loops as a whole, not separately - Smartform

Question

Hi,
In a smartform, each table and it's loop is treated separately.
For example, if a table has a loop into a structure, the table will process each record of the loop.
How do you treat the loops as a whole of several tables? For example,
table 1 loops into a structure for record 1. That record is processed.
Then table 2 loops, with its 1st record having a key that ties it to the 1st record in table 1.
Here is a better diagram:
- Section unrelated to Line items, dealing more with the PO
- Line Item 1 – some general details in a table
>>> Table 1 about the line item, dealing with data about it
>>> Table 10 about the line item, dealing with data about it
- Line Item 2 – some general details in a table
>>> Table 1 about the line item, dealing with data about it
>>> Table 10 about the line item, dealing with data about it
- Section unrelated to Line items, dealing more with the PO
Thanks,
John

Hi John,
Are you looking for nested loops, you can't nest tables, but you can define a loop within a table.
Table 1 would be defined as a table node, then table 2 within it as a loop.  This loop for Table 2 will use the line types defined for table 1, but as you can define an number of line types this doesn't create a problem.  In order to limit your table 2 entries to just those relevant to the current entry of table 1 use the where condition of the loop.
