PR Tax Code Problem

Hello Gurus,

I would want to get Tax code filled in PR create transaction (ME51N). In the field selection group ME51N (in SPRO) which is attached to create PR does not have Tax code field. However the tax code field is present in Field Selection AKTH which does not help me. Is there a way where I could get this Tax code field in field selection ME51N? And do I need addition effort to I pass it to PO? I want this Tax code should be passed to PO directly from PR (as standar SAP allows).

- Regards, SS
