SAP QM初阶如何从ABAP角度区分定性检验特性和定量检验特性
SAP QM初阶如何从ABAP角度区分定性检验特性和定量检验特性 SAP QM模块中主检验特性（MIC）分两种，定量特性(Quantitative MIC) 和定性特性（Qualitative MIC） 对于QPMK_STEUERKZ这个字段值，如下是一些简要的说明： Only quantitative XX = X Only Qualitative = X Quantitative with lower limit XX X = X Quantitative with upper limit XX X = X Quantitative with check value XX X= X Quantitative with upper & lower limit XX XX = X Quantitative with Upper & check value XX X X= X Quantitative with lower & check value XX XX= X Quantitative with lower/Upper/Check value XX XXX= X Quantitative with only
