Subject: Posting key field not found in idoc type ACC_DOCUMENT02

Hello experts.

I am using the IDoc type ACC_DOCUMENT02 for posting FI documents. The sending system is also sending "Posting Key" but I could not find the same in the IDoc type.

Please suggest solution to capture the posting key and process it using the same IDoc type. And my another question is can any std IDoc type for FI exist without posting key?

Thanks,
