Drawbacks on program: Delete Personnel Number (RPUDELPN)

Hi, Experts,

I am using this program "Delete Personnel Number (RPUDELPN)" to delete personnel data. It works fine in Development environment. But it fails to work if T000-CCCATEGORY = "P" (production client).

I am thinking of copying a program and comment the following codes, so the program can go through in production.

IF t000-cccategory EQ 'P'.

MESSAGE e637.

ENDIF.

However, my question is: (1) is there any drawbacks on running this program in production? (2) Why this standard program set this error message? any special reasons?
