affected scope of changing the profile parameter rfc/callback_security_method

[Former Member]

Hi. Experts,

Could you tell me the affected scope of changing the profile parameter "rfc/callback_security_method" value 1 to 0?

Few days ago, I faced the problem that occurring the Internal Kernel Error "RPERF_ILLEGAL_LENG".

To solve this problem permanently, it's need to change the kernel patch level to the latest version.

However, It is necessary to discuss in our team before change it.Therefore I can't change it soon.

Now I'm going to do the workaround changing "rfc/callback_security_method" 1 to 0, according to the Note 2002096.

However, when I change this parameter,I concerned  that the accuracy RFC connection is lowered, or occurring that something bad effects.

If you know about the demerits of change this profile parameter, could tell me about it?

Best Regards,

Hi Naomi,

Kindly go through the note. This will be the least secure one.

Hi Naomi,

I've tried changing this parameter some time back in my test environment and I couldn't find any rfc failures by myself or reported from business

The SAP Note 1971118 can also give some input on the parameter details
