Why doesn’t the system allow me to apply for a certification outside of Functional Area?

Please refer to Paragraph 14a(1) of the Dept of Army Certification Policy and Procedures at https://asc.army.mil/web/alt-workforce-policy-procedure. You must obtain certification in the Acquisition Functional Area (AFA) and level required of your position before applying for additional functional area field certifications. The Functional Area and level required of your position can be found in Section I (Current Position Data) of your ACRB.
