I never worked on Customer exits.I wanted to filter the Query with Material.I have created Customer exit variable on Material.What I need to do is , instead of displaying all the values in F4 help , only one material should be displayed in F4.
This is the code which I have written , but still its displaying all the four values instead of M001.Just its for testing purpose , i want to see how exit works.
DATA VMAT LIKE /BIC/MAMATERIAL-/BIC/AMATERIAL.
IF I_STEP = 1.
SELECT /BIC/AMATERIAL FROM /BIC/MAMATERIAL INTO VMAT where /BIC/AMATERIAL = 'M001'.
L_S_RANGE-LOW = VMAT.
L_S_RANGE-HIGH = VMAT.
L_S_RANGE-SIGN = 'I'.
L_S_RANGE-OPT = 'EQ'.
APPEND L_S_RANGE TO E_T_RANGE.
