Enhanced field data coming Blank

hello experts,

we are working on BW 3.5

i have enhanced FIGL_4 with ref key 1 and 2

i had made Z infoobject for these fields and have enhanced the datasource with code

values are appearing in RSA3 andi have replicated the datasource and fields are avilable in BW datasource.

during 1st load ref key 1 gave alpha conversion error than i corrected it manually by adding zeroes in front and uploaded it but still its value is not appearing in ODS and ref key is blank wheareas ref key 2 value is appearing which is numerc

after that i read a SDN thread and i removed the tick from alpha conversion in info object.

now the field is coming blank again

please suggest what to Do
