I need to create a calculated field in one table based on SUM of another field in another table.
Example: Parts Table: PART_NO, PART_DESCR, etc.
Quantity Table: PART_NO, QTY, UNIT_PRICE
Since Quantity Table can have more than one record for the same part (different unit price), I need to create a calculated field in Parts Table which will sum QTY for the part in Quantity Table.
I need this field for use with SFReports so that user can create a report for Parts Table and show Qty for each part.
How would you do it, create this type of calculated field in SDT? Any other suggestions would be greately appreciated.
TIA,
Dmitry
