Vendor Master enhancement

Hello Gurus,

I have a requirement to add 2 new tabs in the vendor master and I have done everything. In one of the tab, there is a long text field and user enters the long text and I need to store the text into R/3 table(STXH) instead of LFA1.

I have searched for this and I got normal Module pool program and text updating into Z tables.

Please light me on this.

Thanks and Regards,
