SAP table MKPF is a pivotal component in the SAP Material Management (MM) module, serving as the document header table for material documents. It primarily stores key information related to material movements, such as goods receipts, goods issues, and transfer postings. The data captured in MKPF includes the document number, document date, posting date, transaction type, user ID, and plant, among other essential fields. This table acts as the central repository for summarizing and managing the header information of material document transactions, facilitating efficient inventory management and seamless integration with other SAP modules.
SAP table MKPF has 3 primary key fields being MANDT,MBLNR,MJAHR.
If you're only analyzing data from a single SAP instance you may omit field MANT in your relationships as it will we the same across the entire dataset. On the other hand, if you're combining data from multiple SAP instances you need to take MANDT into account.
