We will catch errors in the call transcation explicitly by
using Structure BDCMSGCOLL.
and FUNCITNO MODULE 'WRITE_FORMAT'.

Ex:
Data : bdc_msg type table of bdcmsgcoll with header line,
bdc_tab type table of bdcdata with header line.

CALL TRANSACTION 'MM01' using Bdc_tab mode N
updte S
messages into bdc_msg.
if sy-subrc = 0.
perform Error.
clear bdc_msg.
refresh bdc_msg.
endif.
Read table bdc_msg with key msgtype = 'E'.

if sy-subrc = 0.
call function 'FORMAT_MESSAGE'.

Hi, I have a requirement for locking the fax field in user master records. As you know user can edit the details using the System>profile>own data (SU3), it is causing some security threat to our model. What i want is users should not be able to change the fax field under communications when they get into su3.I have heard of user Exist functionality but don't know how to implement it. Can you suggest something, it will be greatly appreciated.
