Do not consider few characteristics for pegging in SAP APO

Hi,

I do not want to consider few characteristics for pegging of process order to requirements.

How can I achieve this?

In method: /SAPAPO/IF_EX_RRP_PLANNING~PEGID_GET_IO, we can delete the characteristic I suppose that is not relevant for pegging.

But  I am not getting the desired result and system proposing planned order, inspite of existing process order for this reason.

Can any one help or provide code/ syntax to achieve my requirement?

Thank you in advance.

Regards,
