R12 CN Column Mapping, Quantity column not Modified

Hi,

Responsibility: Incentive Compensation Administrator

Navigation: Configuration Workbench --> Collection --> Define Collection Sources and Mapping

For Receivables Posting Transaction Source, when I try to Direct map the Quantity column with ra_customer_trx_lines_all.quantity_ordered, the modified column in cn_column_maps table is not updated to 'Y'.

Since the modified column value is not set to 'Y' the Generate Collection Package is not generating the code to update the quantity column in cn_comm_lines_api.

Attributes 1-100 mapping is working fine, only core/non attribute columns like quantity, customer_id are not mapping as expected.
