Spanish to English Medical Medical: Pharmaceuticals

I am translating a document for a Mexican pharmaceutical company. I need to translate the name of a standard operating procedure and I can't find anything for "lotificado" outside the context of land parceling. Here is the name of the SOP in question:

Procedimiento Normalizado de Operación para el Lotificado de Materia Prima y Material de Envase y Empaque

I look forward to your help. Thanks!
