<b>do reward if useful....</b>
I've checked out EXIT_SAPLFYTX_USER_001 but seems it's related to the pricing/tax records. I am trying to change the <b>header</b> fields' attributes ie. grey some fields out.
For the BADIs, I couldn't find them, guess they are not available in 46C.
Any other info/comments are appreciated!
You want change the fields in disbale or enable in ME21N, first in which fields you are trying the change i.e. diable or enable the field, check the particular screen number and check for any implicit or explicit enahancements, if it is not available take access key and do the changes in PBO level for that particular screen.
