Sanjeet,
I will assume you have already checked the normal things and found no issues; such as:
You have executed the check of Product Allocation found in configuration and found nothing red.
If you are using a Planning Area and Planning book to support your product allocations, you have checked your PA for consistency, and you have checked your Planning books (including your macro books) for consistency.
Your CVCs and your data is consistent between the Product Allocation Group and the Planning Area.
You have run the Product allocation check in //OM17 and eliminated any inconsistencies.
So, assuming no problems up til now, go into VA02 in ECC and again perform the ATP. Again press the Product allocation icon. This time select 'Item', assure yourself that the procedure (and optionally sequence) match those in your configuration.
Then, select 'characteristics'. Assure yourself that the characteristics in your sales doc have a match with one of the rows in your Product Allocation Group.
Once you have found the characteristics of your sales doc, please post a screenshot of the corresponding //AC42 allocation situation that should have been called for this sales order.
Best Regards,
