user exit requirmrnt in va01
I have a following senario, can any any one tell me how to find solution for it.
In sales order line item
material no quantity
after entering these value iam pressing enter iam getiing all the others values for that line item like
MATERIAL DESCRIPTION , CUSTOMER MATERIAL NUMBER
Now for that entered material ie : 40 There is a substitute material is matained in transaction VB12 (change material determination )
ie : for 40 the functional person has maintained as 42.
now when the system is replacing MATERIAL 42 for 40 iam not getting
Customer materail number ( vbap-kdmat ) field for that line item .
Now my requirement is when the substitute material is taken it should find the customer material number ( vbap-kdmat ) also.
ie : it should display customer material number ( vbap-kdmat ) of that line item
How can get that.
