HOW TO CHECK IF A  FIELD HAS NO INITIAL VALUE OR ZERO IN IT .

Answer 1

Hello Vijay,
Please try field Exit as an alternative solution since you need only a mandatory field check.....
To create a field Exit
1)For field exits in R/3 4.6C, execute transaction CMOD. Then type PRFB in the command field.
2)on the top menu...click on Field exit-> create ->enter the name of data element
3)enter the data element required for screen field to be mandatory and Execute
4)another screen comes with a function module name FIELD_EXIT_name of data element
5)Click create and save it to corresponding function group
6)you will get a function module with
import parameter as : INPUT
export parameter as : OUTPUT
7) in the source code write the code :
if input is initial.
message 'SALES FIELD MADATORY' type 'E'.
endif.
8)again to activate execute transaction CMOD. Then type PRFB in the command field. on the top menu...click on Field exit->Activate
now wherever data element is used the mandatory check will come but you need it only for your program ,so in the same screen click on Assign prog./screen tab and write the name of the program and screen number where you want the particular check
I believe field exit are not possible if structure field is on the screen...please do the above and check..you can also run the report RSMODPRF to create a field exit
Hope the suggestions proved useful.
Reward points if it was of any help
