In this field, the system cumulates the quantities in the sales unit from the relevant sales document flow records (field VBFA-RFMNG_FLO). The cumulation ignores the type of sales unit which means that it can add quantities measured in different units of measure if necessary.
The cumulated field can be used to measure the degree to which a sales document item has been fulfilled, and is particularly useful for determining the status as well as for checks and proposals for document references. The field is only used in the standard system if the 'Leading UoM for completing a transaction' in the sales document item (VBAP-KZFME) is not blank. This prerequisite also applies to other systems. This is the only way of ensuring that the sales unit does not change during the flow and that the VBFA-RFMNG_FLO field is filled each time.
