Costing COPA and cost element category '1' for Revenue and COGS

Question

Hi,
In my SAP environment historically Revenue GL accounts were created as cost element with category '1' (costs) and are being posted against cost centres. I know it is not SAP best practice, but it has been working like that in here for years. We have not activated and used COPA so far.
I am currently analysing options of implementing costing based COPA. I wonder if the fact that Revenue and COGS accounts are created as cost element with category '1' should cause any issues with COPA.
I know that in a perfect world it should be '11' for revenues and '12' or no cost element for COGS, I just hope we can leave CE category '1'.
Thank you,
Karol

Hi Ajay,
Thank you for explanation. I feared it would cause issues. However, I checked with one company code that has active COPA.
It has two Revenue accounts: one set as '11' , which is used for most automatic SD postings and other one with '1' category which is 'Other revenues' - sometimes used for automatic postings (configured in VKOA for services) and often used for manual revenue postings.
What I noticed is that documents posted for this 'Other Revenues' were posted against cost centre but also profitability segment was populated. However, it was only populated with sales quantity, no Revenue value field was updated. It must have been configured so it does not show error in COPA but update is not complete in PA table. No COGS split value fields are updated as these postings refer to services.
What I also obseved is that all COGS accounts are set as '1' and are linked to cost centre. But this seems to not affect COPA and it creates COPA document with correct COGS split into cost component category value fields.
So I assume this is only issue for Revenue accounts with '1'. COGS can be left with '1' for time being.
Do you know which config for Revenue account  with '1' might have stopped COPA from giving error while posting invoices in SD?
Thank you,
