Help in LSMW Recording in VA02

Hi Experts!

I need Urgent Help...my client need a massive program to change in VA02 shipping point and storage locations values per item. My problem is that I have already create the recording in LSMW but it is not able to process it in backgorund mode, only manually displaying error, and the error that shows is that the cursor that let me select the item inside the document is not inside the screen....the field i mean is RV45A-POSNR The error says " Cursor field RV45A-MABNR does not exists in the screen" how can i solve it since I do not find other way to enter the item i need to change"....

Please your HELP!!!!

Thanks
