Just remember that INV920 uses the ITH and the CMF file to post to CEA. This would be my biggest concern. Other month end programs use both of those files. Eric Elsberry EPE Consulting Services Cell (909) 238-8519 Fax (480) 830-7513 We are bpcs 6.02 heavily modified. I am toying with the idea of running CEA concurrently with the month end inventory jobs. By cea I mean that we are running batch posting (CLDI501 BTP posting) for cost of goods sold, daily postings. It takes about 2.5 hours to get through all of the posting jobs at which time I run my inventory close and then all of the inventory reports. Takes another 6+ hours. So - I am going to copy the files I need for the inventory reports - they are all read only and go ahead and bring up bpcs. I could come up another 2 hours earlier if I could run my inventory close and then bring up bpcs while cea runs in the background. I am having a tough time believing that posting transactions to the GL would have an impact on ITH ILI IWI files and that they would pick up additional activity after bpcs is brought up. Am I being stupid, playing with fire, or onto something?
