Hi Selva,
1. Is the production order can be settled (production order settlement) if the error exists in COGI against the production order?
Yes you can settle the order if order status is CNF or DLV or TECO even with error's in COGI, but the accounting will not be correct if you have COGI errors.
2. Sometimes, user deletes the entry in the COGI instead of re-processing. I think the entry in the COGI should not be deleted for any reason. Am i right?
Yes you are right. COGI error should not be deleted.
3. How to restrict the user to NOT to delete the entry in the COGI? Is it through authorization?
Check the authorization object C_AFFW_TWK CIM and C_AFKO_ATY CIM
4. I am understanding that due to the below reasons, the entry will be in COGI against the production order. Apart from these reasons, do we have any other reason?
A. During order confirmation (CO15), if the storage location is not available for the backflush items, it will be posted to COGI
Yes
B. During order confirmation (CO15), if the stock is not available for the backflush items, it will be posted to COGI
Yes
5. Assume that, i have restricted the "Over Delivery" for my production order type. And my production order quantity is 5. I am trying the confirm 6 quantity. I am getting the error that "Over Delivery not permitted". Will this case also be posted to COGI?
No. System will restrict to post the entry
6. During order confirmation (CO15), if the storage location is not available for the good receipt item (ie, 101 movement type item), will this case be posted to COGI?
Yes it will post to COGI.
Good practise is before doing settlement - month-end first activity is to clear all the COGI errors and do settlement. Posting dates also is another reason for COGI errors.
Best way is to fail the trasaction in confirmation for any error records through OPK4 config. Under Individual entry screen - Error Handling - Select Goods movement and Terminate for incorrect goods movements.
Many threads from your end are still open. Try to close if you got anwers.
