Hi @Magda 

You should check the Disposition of Quotations setting on the Site→ Manufacturing Tab

If you are set to Ignore or Drop this may explain the behavior you are seeing.

Harley

From help:

Disposition of Quotations:
The disposition of quotation for the site. The possible values are:

Ignore: When Ignore is specified for a quotation line, quotation lines that cross the DTF (demand time fence) consume forecasts in the regular way. If the part is MRP planned then the quotation line will be ignored.
Drop: When Drop is specified for a quotation line, quotation lines that cross the DTF or go past due will in both cases have their Release for Planning flag unchecked. If the part is MRP planned then the quotation will be dropped when crossing current period (system date).
Roll Out: When Roll Out is specified for a quotation line, quotation lines that cross the DTF or go past due will both have their due date reset to the first work day outside the DTF. If the part is MRP planned then the quotation line will be rolled out to the working day after the current period when crossing the system date.

Dear Harley,

you are correct - it was the cause!

Thank you very much for your help, well appreciated! Will help processes in our company.

By the way - additional conditions are:

WHERE  rowstate IN ('Released', 'Revised', 'Rejected')                   -- why Rejected??? 

AND    release_planning = 'RELEASED'

AND    line_item_no >= 0

AND    revised_qty_due > 0

AND    order_supply_type <> 'SEO'
