Data difference between VBUK and VBAK

[#1]

Hello Experts,

I am there in a confusion for the the data entries between VBAK (Sales document header) and VBUK (Header Status and Administrative Data Table). I was in the assumption that # of entries and content (Sales document #) in both of the table would be the same as one is for Sales doc header and other is for its status,while this was not there, some of the entries were there in VBUK which were not in VBAK. I know this seems to be pretty basic question but can anyone please comment over here.

My undersanding is though both are highly correlated, the main difference is that once holds only data regarding the order (VBAK), while the other is concerned with the status of the particular document (VBUK). Hence, not every document type will update status in the same manner and also there might be document types that have multiple status updates. So, that could be a reason why you find inconsisitency.
