BT-156 & BT-1561: Aggregate results for lot groups (e.g. subset of lots in framework agreement)

[odscjen]

The new European Union eForms includes the fields BT-156 (Group Framework Maximum Value) and BT-1561 (Group Framework Re-estimated Value) to appear in Contract Award Notices. OCDS does not support reporting aggregate results for lot groups. If you use groups of lots, please express your interest in this field by commenting on this issue.

Note that, if the lot group contains all the lots in the framework agreement, then awards.maximumValue and awards.estimatedValue can be used. This issue is only relevant if the lot group is a subset.
