Modification of va01

Question

hi;
I was requested to create a Z table for shift which I did. I have also created a new screen that pops up when you press enter after the second screen of the transaction. but when my screen pops up it freeses everything.
I cannot stop the transaction or closes the transaction. How can I save the field entered here in my z table and exit the screen?
could I add there field else were and have them on the header of the va01 screen?

Suggest that you look at the capabilities already mentioned, specifically Additional data B screens, which are implemented at both Header (VBAK) level and at Item (VBAP) level, and INTENDED for use by customer adding additional data fields.  Essentially, you add ZZ-named fields in customizing appends to VBAK or VBAP.  Then modify the appropriate screen number by putting the ZZ-named fields onto the screen, easily done with or without using Screen Painter.  SAP manages updating these fields for you; user exit coding not required, but supported if you need to do something.... If only ALL areas of SAP were this simple, huh?
You can find the screens by looking at program SAPMV45A in SE80...8309 for header and 8459 for item, if I remember correctly.  This may have changed for ECC 6.0.
You should be able to find additional documentation on using Additional data A/B screens in SCN or in SAP Notes.  That said, I've also seen entire sub-applications (screens, tables, db updates, etc.), created and fired by a pushbutton placed on Additional Data B screen.
