To add previous experience to your ACRB, log into CAPPMIS at https://rda.altess.army.mil/camp/, click on CAPPMIS on the navigation bar, click on the ACRB tab, and then the “Edit ACRB” tab. Once in the ACRB Edit, click on the “Assignment History” block and add each position individually. If your previous positions were acquisition related, then make sure that you identify the “Acquisition Position Category” in the appropriate block when editing. Your total months of Acquisition Experience (Section III) are calculated based on the Months Experience column in the Assignment History (Section IX). It includes all of your Acquisition-related work experience where an APC code is assigned in the APC column. If needed, ACRB Instructions are available at the ACRB tab.
