for making the invoice enable flag to YES.

some of organizations show INVOICE_ENABLED_FLAG = N

1) can you enable Invoice enabled flag for all the inventory orgs?

2) compile System Items key flexfields.
Setup/Financials/Flexfields/Key/Segments
query out Flexfield Title = System Items
uncheck Freeze Flexfield Definition
then check Freeze Flexfield Definition
click Compile
make sure it gets compiled.

then make sure:

select inventory_item_id, organization_id, invoice_enabled_flag from mtl_system_items_b
where inventory_item_id in (1906265, 2666665);

select inventory_item_id, organization_id, invoice_enabled_flag from mtl_system_items
where inventory_item_id in (1906265, 2666665);

select inventory_item_id, organization_id, invoice_enabled_flag from mtl_system_items_kfv
where inventory_item_id in (1906265, 2666665);

make sure invoice_enabled_flag = Y for all the output.

3) set profile option "Flexfields:Validate On Server" to No at the responsibility level.

4) relog on apps

5) Then reset the interface records...run autoinvoice master program again.
