Initial Load Serialized Material

Hi everybody:

I am using the standard program RM07MMBL for an initial stock load of serialized material. After the BTC has been created I see it is using the screen SAPLIPW1-0200 to input the serial number, but the standard transaction is asking for the SAPLIPW1-0300. Have you faced any similar situation? It is weird because I have performed this same load in previous projects without this inconvenience.

This is the error Screen

And here you can see the BTC session and program RM07MMBL on line 1185 is calling screen 200

Thank you
