Hi,
I am having the same problem and I was able to close the orders manually. Everything was working great.
My plan was to first clear the orders in Sandbox(very recent copy of PROD) then in DEV(very recent copy of PROD) and then PROD.
SANDBOX:
I compiled list of orders number that were having problems by test running RKKBABS0 program and was able to get the complete list of orders with problems. Closed one or two orders manually. When I was trying to close my the third (I guess) order. I was not able to find anything against the third order. Checked the table AFRP4 and it was empty. Checked from CO1P on results.
DEV:
Knowing I had problems in SANDBOX i was very careful in DEV. I checked the table AFRP4 and saw quit a few entries. After my first run on CO1P on specific order no. I saw that table AFRP4 was empty and I was getting nothing from CO1P on my send order. Error is still there and I cant close the orders.
