Hi Rajesh,
Revision level functionality is not integrated with APO its available in ECC. So you need enhancement here.
Here is one of the approch we tried and its working good
1. We are bringing ECC revision level and its validities through custom program in APO and storing this values in Z-table in APO
2. We have added custom field in product view , reciept veiw using BADI and written logic to show revision level based on requirement date of component. We refer to values in APO Z table and determine revision level of component
Only problem with approch is we are brining revision level data daily once from ECC to APO so data will not be refreshed in real time basis. Secondly Revision level will displayed in product view and receipts view and not in DS board.
Second option you have is add custom field to planned order there is badi available for this APO and populate this custom field during planned order creation, change, re-explosion but I am not sure whether this works.
Regards,
Santosh
