We have to simulate the actual step-by-step procedure to further understand the cause.\n\nAdditional request and clarification to HDMF:\n1. What is the actual alteration they did on ropa_purchase table?  If they have the actual script or SQL used that would be great.\n2. What is the complete step-by-step procedure they did after the alteration?\n\nAction plan:\n1. Replicate the above procedure with the pseudo ropa_purchase table.\n2. Rollforward hdmf_ropa database to test server and see if error still occurs.\n\n
