Pblm in Converting BUOM to Batch specific unit of measure

Hi Gurus

I am Facing a Problem in converting the base unit of measure to batch specific unit of measure.

I have given BUOM in KG.Batch specific unit of measure is PC.

When i do GR for the material in KG with the average wt of the material in kg in the classification view

the system is increasing my GR KG to convert the material to PCS .

I dont want KG to be increased but the PCs to be rounded off to next integer.

How can i resolve this pblm??

NB:- All the settings are done correctly

and all the notes are applicable in ECC 604

Thanks and Regards

BS
