My scenaio is like ths :
If The company has 4 brands of product and according to their sales policy customer must order all 4 brands then only they accept the sales order.
In VA01 when we create sales order, when we enter material in 2nd creen, If all 4 brand is entered then only we can proceed for next step , if one of the brand is missing it will give error mease as ' all brand is not orderd'.
Also exit name is MV45AFZZ - USEREXIT_MOVE_FIELD_TO_VBAP.
Can anybody explain me how to do with coding as material will be entered in table control in VA01.
I got suggestion like :
During runtime of the sales order application all
the details with respect to Sales Order are available
in XVBAK, XVBAP, XVBKD, XVBPA, XVBFA etc... In order to
accomplish your requirement you need to scan through all
the items available in XVBAP and then if the requirement
is met you can proceed further otherwise issue the message
All brands are not ordered.
But can I know what are XVBAK, XVBAP, XVBKD, XVBPA, XVBFA .
Can anybody explain me with simple coding ?
