IS-Retail : Change Merchandise Category for an Article

Hi,

We are using SAP R/3 4.6B Version. I need to Reclassification for an article but not able to proceed further. I want to change article from one Merchandise category to another.

In SAP 4.7 we have transaction WRCR where we can reclassify an article from one Merchandise category to another.

Can any one help me in in this regard, your inputs are much appreciated.

Regards

Raj
