Revaluation of the material for SAP Retail ( like mr21)?

Hi Expert, I want to know if exist some transaction to revaluation material, like mr21, but for special aplicaqtion in SAP Retail. I´m working on with 18 plant, so is very hard to revaluation all the items in each  plant with the MR21 ( although that I´m using a LSMW for Mr21 ) .

What is the best practice in SAP Retail?

Thanks a lot.
