How to gray out fields in VA01 & VA02

Question

Hi All,
My requirement is to restrict manual entries of line items.
While creating a  credit memo with refrence to billing document the items from billing document gets copied to this document.
User wants to restrict entering more line items apart from these.
Therefore the rows after the last line item should be grayed out i.e in display mode. (Not the columns).
This should happen in VA01 & VA02 transaction.
I have found the Userexit_field_modification in include MV45AFZZ.
Also the screen nunmber is 4902 and table control TCTRL_U_ERF_GUTLAST whose screen input should be 0.
Please let me know if there is some other way by which this can be achieved also if this is correct; then how should I proceed with the logic.
Thanks in advance.

Hi,
For doing so you can use the concept of the transaction variants. Using transaction variants, you can do the below:
1) Make fields mandatory on screen
2) Hide fields on the screen
3) Default values on screen fields
4) Make fields input disable on screen.
Hence for doing this, go to SHD0 transaction and do the recording for the standard transaction. Once done Save the transaction variant.
Finally from menu((tab page: Standard Variant in SHD0): Activate as Standard Transactions variant.
Give the Name as your Transaction variant name.
Once you active the transaction variant as the standard variant, then if the std transaction is called, the screens which you defined in the transaction variant will be called.
No code changes need to be done. The transaction variant will only change the appearance of the screens
