求翻译：Like I told you yesterday, Larry has plan to substitute the OCA material by PVB and is in the process of doing so therefore we have to watch ordering of this EL92630 material for the perfect timing to switch over without causing excess inventory than we needed. Can you find out how long these 84 rolls could carry over factory’s demand ? 2-months ?? or what else ??? Let us know ASAP是什么意思？
