Pop up in standard screen

Question

Hi,
I have a requirement which is as follows-
User will create Order wherein he will give the
Sales area customer details.
Once he enters plant and hits enter, a popup should appear which will contain the appropriate storage location for that plant (maybe radio buttons).
he will then select the actual storage loc.
I want to know how can we have a pop up in standard screens.
Please pour in your comments.
Thanks in advance.

Hi,
Pop up can be implemented as a custom function module. You can use a standard pop up as reference which is SD_PARTNER_ADDRESS_DIALOG (you can check it in SE37; this is called from include LV09CF70)
Develop a similar FM but with storage location and call this pop up function in user exit USEREXIT_CHECK_VBAP (include MV45AFZB). You can implement some code along the following lines.
If <VBAP-WERKS not initial> and <any other condition for which pop up should be applicable>
      Call the pop up custom FM
       (This function module can provide a field storage location with drop down showing the values relevant for VBAP-WERKS)
      Whatever value user gives in the field, copy it to VBAP-LGORT.
EndIf.
Since this user exit is designed to execute everytime a user changes any field at item level, this is bound to give a pop up whenever user enters a plant.
